body work question rear valence, can I fix this? Progress with boring pics Options

[theleschyouknow]

I've had my car for about two years first year -what I call the year of living dangerously
I drove it whenever the weather allowed including a 914 weekend in the talimena hills
after a brokenclutch cable clevis it's been wheels in the air for close to a year I've been cleaning the engine and trans and suspension arms and cv's/axles and shocks & springs and engine tin I can reach of 40+ years of grease and dirt -a bunch of it likely from the leaking cv's which I'm sure I'll ask about soon in another thread
so here's my question for this thread:
my rear valence has one 'big' dent in it and couple small wrinkles in the bottom 1/4" or so 'return' flange that defines the bottom edge
pics following

having never done any kind of body work before this seems fairly straight forward to repair
what are the minimal tools required?
what kind of results could reasonably be expected?
could I (easily)screw it up beyond repair?

thanks for any comments or suggestions

thanks for the support Darren I'll split the difference in weather temps with you anytime between mid-May and mid-September if we can work it out

I did get a chance to do a little more hammering tonight no pics as it got too dark but I feel like I have done quite a bit of good and some bad

I've gotten the bottom much closer back to the original shape with a bit yet to go I have also put a few dings and high spots in it but I think I can work those down after I get the bottom shaped right

I'll have some work to do on the return flange as Ive flattened it out a bit to make moving the metal in the ~90 plane on the wide side a bit easier

one question regarding the bottom return flange:
there are three support 'brackets' on the backside of the valance two 'vertical' ones about 3cm wide at equidistant midpoints and one about 20cm that mirrors the muffler cut out for backside support. At several spots where the flange meets these brackets to varying degrees it looks like the flange is either mis-shapened around those bracket connections or the brackets themselves are out of alignment. Anybody else notice this? I haven't had much luck moving both layers of metal but I haven't worked them much -still concentrating on the main problem area
