Hmmm... I guess I'll start with the jacks. What's the best way to clean them? Just spray with deoxit and insert a cord 1,000 times?

While I'm inside, should I stay away from any big parts that might knock me across the room?

What else can I check while I'm in there? I'm going to look for swelling caps, discolored bits, and then flip it over to see if any of the solder needs re-flowing (I guess). Any advice would be greatly appreciated.

MarshallJMP:
Leave it off for a few minutes before you open it. For the rest Kim has a point with ESF , if that doesn't help you can go in deeper.

1,000 times seems a bit overkill.  998 times would be more appropriate.   ;)   
But seriously, if you need a number......10 is fine.    Spray into the jack and/or on the male 1/4" plug and give it to it.  I can't remember for certain if those jacks are enclosed (but I think they are) so the switching one will be hard to get at the switch contacts.  Best you can do there then is just blast the cleaner into the jack and hope it gets there with the repeated plug inserts.  Also there's an internal cover to remove in order to get at some stuff.  You'll see it when you open it.

And while you're in there, see if you can spray into the front panel pots.  There should be a little access notch or hole to get the spray into the assembly.  Give it a shot of spray and work the knob around.  Then I'd say if you don't see anything obviously wrong in there, button it back up and try it out.     Good luck, we're all counting on you.   :)

wow, the pressure is intense

I sprayed the jacks with deoxit and inserted a cord about 998 times last night, I did the knobs as soon as I got it, and have had no issue with scratchiness, so I left them alone. Gonna plug it in tonight and try it out. It usually takes a good half hour of playing before it acts up...
