Wait 2-3 minutes, test the positive lead on the cap can for voltage to verify it's not storing 500vdc anymore, then have at. I'd leave the alligator clip plugged in and the plug in the wall to keep a ground on my amps, but who knows if that has a death cap in it. For you, I'd alligator lead the ground prong or chassis right into the wall ground.
Seriously, I'll say it again, 500vdc from a cap across the chest can and will stop your heart. Be careful! I've been hit twice, not across the chest, and it tensed me up so bad I couldn't turn my head for a week.
The mess of wiring might be on purpose. Twisted pairs of wires are normally AC runs, and untwisted, they'll cause hum in an amp. Does the amp even work?

Wow! You leave them plugged in when you work on them! You can still get shocked if you touch near where the cord comes into the amp. This is how I've been zapped before.
