The first
MNSSHP is not until September 13, so there will not be a map available until after that.
Here are 2 pages with information about last year. There is some information that will help you with planning and they usually scan in a new map very soon after it is available.

The parade and fireworks are pretty much the same from year to year. The characters that appear may be different. And, the biggest difference this year will be that Toontown no longer exists, so some of the things that took place there will take place somewhere else.
When you are looking at maps on the Internet, if you find a map that includes Toontown, it is an older map and not up to date. If you can't find a newer one, you can just block Toontown off the map.
You can download a current map of Magic Kingdom and the other parks from this site:

This site has a list of pressed penny locations, but it is not up to date since it includes Toontown and a shop called Tinkerbell's Treasures that no longer exists. I will see if I can find you a more up to date list.

Also be aware that sometimes you will find a pressed penny spot has been moved, the machine no longer has the pictures that are on the list or the machine is not working.
The Photopass locations also do not always have someone working in that spot. They will have at least one all day near the park entrance at each park. Other locations may not have a Photopass person there during times it is not busy.
I don't know of any maps that show Photopass or pressed penny locations.
I really like clanmcculloch's suggestion to download maps to a thumb drive and then take them to a place like Kinkos to print. I have printed things before at Office Max or Office Depot. Those work well too.
If you print several copies of each map, you can make notes about different things on the maps. Like one map has the penny locations marked, one has quiet, decompression spots, one has photo spots.
A lot of people who have anxiety issues make themselves a personal tour folder with things like maps, lists and plans for each day. You might also find that to be helpful.
