I think T_R covered most of my thoughts on this. I would add, though, that form is far more important than weight, especially when just starting out. Watch your movements and your muscles, directly and in the mirrors. If there is a trainer at your gym, pay for a session or two, and get any form corrections taken care of at the onset. It's far easier to learn the correct movement, than to forget the incorrect one. Also, (especially when just starting out) I don't think it is to your advantage to go to failure. You want, eventually, to 'burn' the muscles at each training session, but one of the biggest mistakes that I see people make in the beginning, is, they train so hard that they are immobilized the next day or two. This usually prevents them from working out when they planned, and has - on occassion prevented them from doing the job they do to make a living (such as your case - where you must lift to work).
As for AM vs. PM. Are you a morning person or an evening person? Some people wake up with all kinds of energy, and have more productive workouts early in the day, regardless of how clean and thorough their diet is the rest of the day. Others, however, are shit in the mornings. They hit the snooze like 4-5 times, and really need a couple of hours to 'come to'.
Try each method, for a solid week (one week working out AM, the next week working out PM) and see which feels 'right' to you.
