Removing/Spraying Valve Cover, need help, will do how-to article Options

[DSRT-FX]

hey 6gc'z,
Been on 6gc.net since last year, and i've always wanted a red top. Much like a Honda Type R and a Nissan Skyline engine. Although toyota are alot better Nwayz i've got a few dillemas:

i. How in the world do you remove the valve cover? (4 bolts below the ignition leads?)
ii. Do I need to remove the spark plugs first? and other wiring?
ii. If I do remove the valve cover is there going to be an abundant volume of oil threatening to devour me? lol
iii. When I need to put it back on do I need to replace the head gaskets?
iv. Any other information i need to know?

Thanks for your time guys. If all things go well i'll be definately making a how-to article on this =] -R
