If you don't have any indication of head gasket failure, leave the heads alone. They should be fine. Replace the o-rings for sure, and yes, soaking them should be fine. Be careful not to dislodge any chunks into the nozzle that may plug them up.
Yes, you should also clean the throttle body, but remove the maf sensor first, and use an 'intake safe' cleaner, not carb cleaner. A toothbrush may come in handy, too.
Now would be a good time to change to a 180° thermostat, too.

Anything special I should know about tearing it apart and putting it back together?
Would you bother tearing off the heads and replacing the head gasgets? I will be replacing the o-rings on the injectors ... Is there any way to clean them up or test them? I was planning to soak them overnight in injector cleaner and than try to clean them up by hand. Will this hurt anything?? Should I clean the throttle body??
Is there anything else I should be replacing while I have it apart this far??
In the spring, I plan to replace the timing chain, oil pump, and oil pan gasket. I'm trying to make this car last for a long time since it'* my every day driver.
Any advice will be appreciated ....
This is a great site and I've learned alot from many of you. Thanks.
