The Fastpass system is still free. I am not sure of all the rides that include it but it includes the more popular rides. Also, I am pretty sure that they have built it with all of the new rides recently.
Nemo dosn't have it. Don't believe MILF does either.
Off the top of my head (* = an attraction I'd reccomend using it for if you need to hit the attraction, ^ = a show and thus don't really reccomend using a FP there.)
Magic Kingdom
Jungle Cruise
Splash Mountain*
Thunder Mountain*
Peter Pan's Flight*
Mickey's Philharmagic^
Space Mountain*
Buzz Lightyear*
Stitch
Many Adventures of Winnie the Pooh
Epcot
Body Wars (although closed and probably not in operation when it is open)
Mission: Space (the later in the day the shorter the line... almost non existant closer to park closing, rarely needed for Green/non spinning side)
Test Track*
Sorin*
Living with the Land
Honey I shrunk the AUdience^
Maelstrom

Now if you're lucky you'll win a dream fast pass giving you one fast pass good at any time during the day you won it for every attraction in the park you won it in (so in Epcot you'll get a FP for every attraction listed under Epcot).
