I wouldn't ever recommend raising flap at that stage, all sorts of odd things may happen, what would you do if you then got assymetric flap for example?
Use the correct techniques, try out some shortfield landings on a longer runway until you get a feel for the machine, before trying short strips. The 172 is an incredibly docile machine, it just needs a bit of practise like any other.
Try doing some upper airwork at speeds just above the stall, this helps build up "feel", something I think that is more important than numbers sometimes.
FD's suggestion is a good one.
