i have not posted any pictures of the back of my head until now. will rogaine help? i ask because i have a coupon for $10 off. i obviously don't want to lose any front length, should i treat the spot in the back or concentrate on letting the front grow longer?

I would suggest that you go see a dermatologist. They should be able to examine the back of your head and tell you if there are any hair grafts left that would respond to treatments.
My understanding is that rogaine only affects the hair that is still in the stages of miniaturization.
If you have trouble growing out your hair in the front this could be due to MPB also.
Before a hair falls off permanently it's growth cycle will shorten, and within each new hair growing out of the graft the individual hairs will grow shorter and thinner each time until there is only "peach fuzz" left.
