1.) what type of grease du you use to lub cabels? dose it matter?

I use triflow when I first install the cables. Change the cables once a season; they are only a couple of dollars each.

2.) how do you take care of your fork, lub, dirt? (my manual is crap and i hope to upgrade to air)

I haven't really done much for my forks, although one is due for a service. There are stanchion lubes out there if you are getting stiction.

3.) how do you clip into egg beaters? you use the same type of shoe clip in thing right?

Get a pair of SPD compatible shoes, and mount the cleats (instructions should be with the pedals). They can be adjusted a bit fore-aft, side-side, and rotationally, to get your feet into an ideal position for you.

4.) what do you do if you get a crack in your frame? can you fix it yourself? im thinking gorilla glue.

Get a new frame. Is your bike under warranty?
