So I paired the iMac with my Bluetooth keyboard that I use for my iPad (Verbatim folding keyboard) and it works. I'm guessing it may be a hardware issue now..?

Is the iMac keyboard a wireless or wired keyboard?

It is wired. I've isolated some of the problem keys.
None of the top row work (F keys, volume, etc)
Q types QT
T types QT
G types *a and the copyright symbol, as does A
Delete does nothing

Sounds like the switches under the keys may be damaged.
© should be opt-G on UK and US keyboards, å would be opt-A.
Almost certainly hardware, anyway.
I see your profile says you're on 10.5.8 (Leopard).
If you decide to replace the keyboard with a new one, be aware that the currently available keyboards from Apple require Snow Leopard 10.6.8 or Lion to function correctly, so you may need to look at second-hand sources.

The first set (A and Q) have a horizontal offset of 4 keys.
The second set (G and A) also have a horizontal offset of 4 keys (and seem to add Option to the mix).
This type of problem, as noondaywitch indicates, is almost certainly in the keyboard itself, usually caused by a liquid spill shorting out circuits.
There is no means of mechanical repair for those keyboards; replacement is usually the only choice. You need not use an Apple-brand keyboard; if you do want an Apple=brand one, as noondaywitch noted there is an OS X version issue with regard to current offerings from the Apple Store. Other brands are usable; the main concern is that they be compatible with the Mac startup command set. The description of such should indicate wheter or not they are in compliance with that. In general, Macally keyboards are compatible.
If you want to take a chance in trying to fix the keyboard, you can try washing the keyboard. No promises that it will work; but, trying it won't hurt if you are prepared to replace it anyway. Couple of ways that have occasionally worked -
• Dishwasher. No soap, warm water only.
• Hand-dunking and sloshing in warm distilled water (like what is sold in grocery stores for steam irons). Do it once, then drain and do it again with a fresh batch of warm distilled water as a rinse.
Once washed, put it out to dry for 2 or 3 days. Place it vertical on a towel or other absorbent material. Don't add heat - a plain fan is okay, but no blow dryer.
The trick is to get it thoroughly dry before attempting to use it.

Thanks for all the help! Going to the Mac store today to get a new keyboard, and I'll pick up snow leopard while I'm there.

I think Snow Leopard is only available on line now;
And the 10.6.8 combo update;
