Welcome to MB! Any question you have will most likely have an answer from someone.
Definitely read the Passporter or Ultimate Guide. Allears.net is an awesome sight for everything WDW.
We always have a car and find that it saves us loads of time while we are there. We still use the transportation around MK if we are going to/from the resorts for ADR’s.

Night Time Ideas…
Water Pagent - You can watch it from the beaches of the MK resorts on the lake.
Boardwalk - Have dinner either at Epcot or a BW restaurant and stroll the boardwalk. There are entertainers that are fun to watch. Also, try renting a surry bike. Bet you can’t get up the hill between YC/BC and the Dolphin/Swan resorts.
Play mini golf with the coupon you receive with your package (if you booked a package). We love Winter Summerland’s course. Great theming!
Of course make sure you catch the Spectromagic parade at MK, Wishes, Illuminations and Fantasmic.
And, make sure you check out DTD with all the shops and restaurants. Cirque Du Sole (Spelling ha ha ha) is awesome too.
