So this M&M X teaser has me all exited and I done goofed and installed M&M 1 through 8, now my goal will be to try and play through ALL of them (yikes). I've played M&M7 many times but not the rest and I am wondering if you guys know of any good websites / fan-sites / wiki's that are useful resources for these games, stuff with FAQ's, walkthrough's, maps, and helpful tips and tricks. Spoilers be damned, I don't care I just want tons of info about everything.

So if it's not too much trouble can you guys link me some sites that would make for good bookmarks while playing each game. Big thanks in advance.

I can also recommend the guidbooks that come with the games. Very helpful.

Yeah the guidebooks are a good idea. For the earliest games they don't offer full solutions, just hints (and maps) but I'm pretty sure that the guidebooks for World of Xeen (MM4-5) contain full solutions to everything.
