Help me out!

[MassTrauma]

soo....I got a job delivering pizza (right when gas goes up...) ...and I get the CEL on. Well its cylinder #3....figured it was a easy fix...hahahahaha
In the end its the head gasket...(geting coolent on the spark plug)
but here are the questions, if you guys would help a 18 year old out...

Whats the best way or trick to get the timing belt off the cams?
Any good websites or posts on a timing belt job? (1996 Lexus Ls400)
If I get a machinest to bore(I guess thats the right word) the valves out do I have to go and tune on a dyno to get the full effect? Or can I just bolt the heads back on?
Next, good performance ECU? (That dosnt knock of my head.)
Thats it for now, any help at all is GREATLY appreciated..

You know. There is/was. Where would I go from there or what should I do about it? ...Thanks for putting up with my ignorance...I just wish to learn.
And yes SR8tt, that helps a boat load. Thank you.

Also not on top of the spark plugs but inside cylinder camber on cylinder #3..
