Make sure you make a note in which direction all the fans in the PC are
blowing. Usually there is an arrow on them which tells you which way
they blow but you can also feel it by holding your hand in front of
them. The replacement fans need to blow in the same direction so think
about that when putting them in.

Don't worry. It's nothing like it was in the eighties when stuff fell
apart by merely looking at it (except for the IBM keyboards).

As far as I know touching something that's properly grounded should do
it. Maybe something like gas/water/heating pipes (unpainted bare metal).
Stating the obvious but please do disconnect the power cord before doing
anything and wait a minute. If the power supply itself has an on/off
switch (usually at the back) then leave the switch on and disconnect the
power cord. If it also has a light you can see it go dark. Even after
the power supply has been disconnected it can still have a charge so
don't go poking any metal objects in there unless you want smoke coming
out of your ears.

Don't think so but refrain from touching the actual chips. And do it
near a lamp with a lot of light.

There are a lot of instructions here:

Correct. You only need a really small amount of it. It's only needed to
fill any air pockets (=lot's of heat getting trapped) with thermal paste
between the cpu and the heatsink so the heat is guided away through the
heatsink instead of getting stuck and frying your cpu.
Clean both the heatsink and the cpu so the old stuff is removed. Only
then you apply thermal paste only on the cpu (not on the heatsink). Read
the instructions at the link I gave you earlier.
> If I add to much thermal paste, what do I do about it?
Remove it with a credit card or something non-metallic similar. Read
through the instructions at the link I gave you earlier.
I usually remove dust with a vacuumcleaner where I can without touching
anything in the PC. If you want to do it the fancy way get a can of
compressed air and blow the dust straight out.
