Dont get discouraged, just fix it like youd eat an elephant.
As for the floppy leaf, I can empathize with worn out springs, although not quite that bad. If you dont want to tackle taking the leafs apart, a decent temporary solution is to stick a pair of superior 11-1020 leaf spring helpers on them. Amazon has them for around 35 bucks and you just bolt them under the rear of the leafs, no dissasembly required. They wont make the springs work like new, but theyll keep them alive for a while longer.
