Working on the front derailleur it had been on the small ring so long it didn't even want to move, so plenty of lubricant got it moving. Somehow it jammed while still on the stand and I was really surprised & disappointed to see the rear derailleur go limp. I'm pretty new to wrenching and I was hoping to get together with @3speedslow this w/e for a wrench-fest but a schedule conflict came up.

It's a Raleigh branded SunTour according to Law, anyone have any advice or YouTube links on replacing a tension spring? I found one from RJ the bike guy but it was a more modern derailleur. Here's a couple of pics of the bent ring and rear derailleur -- help !
