Since you have no existing data, you can ignore the advice about backing
up.

If it was installed from RPMs (the likely case on a Red Hat system) then
"rpm -e" is what you want. You might also consider installing the new
version from RPM rather than building your own. I'm not sure if there
are prebuilt binary RPMs of 7.4 available for RHAS 2.1, but if not you
could grab the source RPM (SRPM) and build it yourself.

No. If you were wanting to run both versions in parallel then some care
would be needed, but you don't seem to need that.

pgsql-admin would probably be a better source of advice than
pgsql-novice.
