Money is really really tight bro, So cant really go and buy food period at the moment.(Live in a poor 'hood, Middle of a court situation where i have to pay up a couple G's, Tough times...)

How many reps would you suggest? Add weight and do less reps? Same weight and less reps. Also more sets then?

Also on my cardio i walk fast, No jogging or running on my treadmill. Not the greatest of quality. But personally i dont see how cardio can lead to muscle loss... I'd think just more calories being burned...

I'll deff look into more shoulder excersises too, When would you reccomend i do them? Where in my schedule looks good?
