whooooaaa...this one is gettin' fierce...
Anyhow, back to the important part...MUD...once you get used to it, you'll love it, but like most people say, it can damage the trails...so I try to avoid it anymore, just outta respect for others and the future of the trail...
I've been using Conti Vertical Pro's since I got stuck with some packed-up, mud-coated tires that wouldn't do anything BUT spin last winter...it's about time for some new skins, so I'm not sure where I'll go...maybe the IRC Trailbears...
As far as the bike, wash it GENTLY as soon as you can...dried mud never really goes away it seems...Lube everything (but follow directions, too much can be TOO much...)
Last summer was really wet, so I washedmy rig everytime I rode (or every other time)...Mud, water and slime can really eat some stuff up when they dry...
Despite what some say, you learn to love the mud...it's just another form of dirt, like an evil twin...
