Welcome to the DIS! I'm sure you'll find a lot of helpful advice here! As far as resorts go, you may want to check out the information and maybe post some questions on the Resorts board:

I know I've gotten some great advice and answers to my questions over there.
There is monorail service to the Polynesian, Grand Floridian, and Contemporary Resorts, but all of the resorts have some combination of bus, boat and/or monorail transportation available (for example, the monorails only go to Magic Kingdom and Epcot, so even at the "monorail resorts" you will have buses to the other parks and downtown disney).
Many here have used
Dreams Unlimited and were very happy with them. You can get a cost estimate emailed to you:

You may also want to check out Mousesavers:

to see what deals may be available. I would recommend signing up for their newsletter as it often contains links to specials not available to anyone else!
Most PS (Priority Seatings) for meals can be made 90 days in advance. Depending on when you will be going in November and how busy it is, you may or may not need to make them that far in advance. There is so much information available here:
http://allearsnet.com/din/dining.htm that should be able to help you decide where you would like to eat. Along the left are links to menus, photos, and which characters you can find at which meals!
Hope this helps!
