The 7AFE cam cover is very easy to take off. All you need to do is to remove the HT leads, remove the power cable going to alternator, then the four (10mm i think) bolts and lift off carefully. Paint the cover replace the seal then reverse the process.
As for the inlet, this is a lot more involed. (doing this from memory)
Remove intake piping,
disconnet injector wiring
remove TPS plug
remove water pipes from TB
remove all vacumm pipe going to inlet such as break booster, map sensor
Then carefully remove the bolt attaching the inlet to the head think they are 12mm, and the brace holding the inlet up.
Then you can wriggle the inlet off.
I have probably missed out a few bits, but this is from memory from when i did it a fair few years ago. If you work at it methodically then it shouldn't be too much of a problem.
