I use
FitDay to keep track of my calories, but any similar site will do as long as you record everything you eat. I think fitday tends to over-estimate the amount of calories expended, but it could be just me. I've been cutting at 1200-1500 a day, though i've hit a standstill so i'm kinda stuck as well. Not sure if i should increase or decrease my calories.
I use some online calculators for bodyfat percentage because i don't have calipers yet either, though i'd take their numbers with a grain of salt. One site i use, i call it the optimistic one, is here:
Home Body Fat Test
The other one i use is this one, it's apparently based on some system they use in the navy:
Body Fat Calculator I call this the pessimistic one because according to it, i've got 34% bodyfat! Compared to the first one that usually says i'm 24-25%. I'm not sure which one's more accurate, but i think i look closer to 25% than 34%. These sites might be good enough as a rough guideline, but i'm definitely getting some calipers as soon as i have the money.
