Sure, sure!!! I'm a WDW and TDR lover! Some of these are tips, others are interesting facts, advice, etc. Believe it or not, Tokyo Disney Resort is about the size of
Disneyland Resort in Anaheim, CA. It has a complete monorail system that links Welcome Center/Ikspiari, Tokyo Disneyland, Bay Station, and Tokyo DisneySea.
I believe that TDR is the cleanest Disney resorts. If memory serves me, toilets are very spacious and are usually air-conditioned. In front of the toilets, there are usually some drinking fountains.
Note that the tips that I'm going to share with you is based on my experience in 2004. Some of them might change, others stay the same. These tips work well if you are touring by yourself or with your family. If you've a guide, I don't think that these advices will work very well, but you may read it just for your reference.

MONORAIL
The best way to travel between the official hotel (Hilton, Tokyo Bay Tokyu, Sheraton, etc.) Tokyo Disneyland, DisneySea, and Welcome Center/Ikspiari is to catch the monorail. The monorail size is 1 1/4 longer than the monorails in WDW (a monorail driver in WDW told me so) and it is operated automatically. It is a little bit different with the one in WDW. If you board the monorail in the front, you can walk to the back of the monorail. This is different with the monorail in WDW because you are "locked" in a monorail car once you are seated. There are "real" handrails in case you are standing. The windows are somewhat extraordinary, 'cause they are Mickey-shaped.
There are four stations, as I have mentioned before.
STATION 1: Welcome Center (I forgot the real name, but it is definitely the place to welcome you)/Ikspiari
STATION 2: Tokyo Disneyland
STATION 3: Bay Station (the place where 5 official hotels are located)
STATION 4: Tokyo DisneySea
As of 2004, you ought to pay a certain amount of money in Japanese Yen if you'd like to catch the monorail. And I think you ought to ride the monorail, since there are no other way to travel between the resort unless you take the highly expensive taxi.
Be honest... is the best tips that I have, and it's interesting as well. When you buy a ticket at a vending machine, you may choose to buy an adult, child, or ... (I forget) ticket. This is somewhat interesting. If you're an adult and trying to buy a child ticket... The vending machine will not know, the ticket tag machine won't also recognize, but the guards in every station will. Whenever you buy a child ticket, it will make a short sound if you insert your ticket into the ticket tag machine. If it make sounds, then the one who enter should be a child, not an adult! But if an adult enter with a child ticket, it will still make a sound, and the guards will know!
BUSES
Buses operate between the 5 official hotels (see HOTELS section) and Bay Station. The other buses operate between JR Maihama Station (see JAPAN RAIL section) and Welcome Center. All of them are FREE of charge.
If you want to transfer between Tokyo Disneyland and Tokyo DisneySea ,you have to use the monorail.
HOTELS
This section is only just in case you're staying inside TDR or interested in TDR hotels.
TDR has 2 true-official hotels and 5 official hotels.
The 2 "true-official" hotels are MiraCosta and Ambassador, all operated by TDR.
The other 5 are operated by Hilton, Sheraton, etc.
PARKS
TDR has two parks, one is Tokyo Disneyland and the other one is Tokyo DisneySea. Tokyo Disneyland is almost the same with Magic Kingdom, Hong Kong Disneyland, and Disneyland Park. But the entrance is completely different and it doesn't have Main Street. Instead, it has World Bazaar.
Most of the attractions are copied from Disneyland or Hong Kong Disneyland and sponsored by local companies.
Some of them are completely different, like Pooh Honey Hunt. The name may suggest you like riding The Many Adventure of Winnie the Pooh, but it is totally different!
Tokyo DisneySea is a very unique park, and most of the attractions are truly made by TDR. Many of the attractions you found here will not be able to be found in other Disney theme parks.
FASTPASSes are free as well and can be operated like the ones in WDW or Disneyland Resort.
SOUVENIRS
Are you looking for pins? There are only a limited selection of pins I believe (as of 2004). TDR is famous for its creative souvenirs. Most of them are "edible souvenirs", such as cookies, chocolates, etc. And they are packed in a very creative boxes, such as pirate ship, canon, rocket, etc. They might be expensive but if you buy some, I'm sure that you'll not find anything like those outside Japan.
If you don't have time to buy souvenirs inside the park, buy at Bon Voyage! located inside the TDR. Ask cast member for directions. Many of CMs DO speak English in case you are worried.
IKSPIARI
If you are wondering what Ikspiari is... It is the downtown of TDR. It is indoor, different with the ones at Disneyland Resort, WDW, and Disney Paris. It has many, many shops. Most of them are NOT Disney related.
Ikspiari also has some selection of good food. There is a very good Chinese restaurant (I forget the name) and a burger specialized restaurant. If you like burgers very much, you may try the Hawaiian burger at ... (I forgot, but it's definitely a Hawaiian burger). It's the best burger I've ever eaten.
JAPAN RAIL (JR)
Maybe you won't utilize JR, but I give you some advices. The nearest station to reach TDR is MAIHAMA station. From there, you can catch a free bus to transport you to Welcome Center. If you are staying at the 2 true-official hotels or the 5 official hotels, you ought to use the monorail. Otherwise, you will have to catch an expensive cab.
If you need more advices, post a reply, and I'll give you advices based on my experience there.

My daughter and wife always say that Tokyo Disney Resort is the best Disney resort in the world, while I and my son think that TDR is equal with WDW, though they have different atmosphere.
Have a safe, magical, and wonderful trip!
