Massive first post, I know, but if someone has the free time they might take a look:

so I just started weightlifting a month ago, something i've never done before (i've always been more of a endurance guy), and am looking for help with the routine I created for myself. I hear that I need rest periods so I only go to the gym every other day, but when I do I generally lift the same weights.

My routine is as follows (every other day):
10 minute cardio warmup (elliptical or treadmill)
free curls (25 lbs, 2-8 on each arm)
bench press (115 lbs, 3-8)
tricep press (175, 3-10)
leg press (280, 2-10)
calf extension (250, 3-10)
incline press (140, 2-10)
pec fly (110, 3-10)
compound row (130, 2-10)
lat pulldown (125, 2-10)
abs machine (120, 2-10)
obliques (110, 2-10 each side)
lower back (120, 3-10)

then every night at home:
30 pushups
30 situps
free curls (25, 3-8)

what kind of results can I expect from this routine? Am I doing the right things so not as to damage by body? My goal is not really to get massively buff, but I guess to gain some muscle. I dont have much fat to tone - i'm much too skinny - and have set my tangible goals at weight gain only, as I hope to reach 160-5 by summers end, if possible. I'm at 5'11" and started 140 pounds (now more like 145), and have kept up a relatively steady diet (i have an insanely high metabolism, and end up eating maybe 4000-5000 calories a day). I have started to focus on protein a lot more with a proteinaceous snack after each workout, and about my fats intake (less mcdonalds, more milk etc). I'm also looking for an easy protein source in a shake, if anyone has any suggestions for brands/eating habits. Anyhow, if anyone has bothered to read this far and has advice, i'd be grateful; I really don't have any experience with weights, and could be doing it all wrong. Thanks!
