Why not, if you've got the energy to last for so many sets? Or if you don't, you can still do full body but cut down on some sets so that the total sets isn't too much for your body to handle. Also only do full body if you know you can recover in time for your next routine workout for those body parts.

Normally if I can't gym and I can't afford to be flexible enough other than to do full body on one day, I will just let it go and let the skipped body parts take a rest. That's just me though, you can handle it any way you think fit

Haha your weight doesn't seem too bad. I think you've got potential, go go go !

Your bench will increase with consistent training, form and diet... Anyway don't worry too much about how much you can lift.

I think you did enough workout sets... I myself only do 14 sets on chest day. Just make sure you are not overtraining in the gym!
