how high is a little high?
a high idle on a cold start is normal. 2k or so RPMs.
rough idle could be coils, plugs, or a vacuum leak.
pulling to the right could be bad tire, low tire air pressure, a bad alignment, or worn/failed suspension pieces.

IAC would account for a low idle, or a hanging high idle, not really a rough idle.
if the car has near, or more than 100k, you should do plugs.
the autolite 764 plug is popular and cheap.
the autolite 103 is a more performance oriented plug, but not really needed on an all stock vehicle. i would recommend it in combination with a tune though.
you can pay more for a platinum plug with a longer service life if you wish.
also check the vacuum lines on top of the intake, they break down from the heat and fumes and can leak.
rotate your tires, if the problem persists, you probably need a front suspension rebuild. most of these cars do.
