I'm not 100% but I think you can get a set of pwerblocks (which are adjustable dumbells) for about the same price as a bowflex. You can work every single body part with dumbells and an adjustable bench and you don't need a spotter. You will also be strengthening your joints, tendons and stabilizing muscles (you don't get that with a bowflex). Do a search for "powerblocks"

You have the right idea 6-7 meals per day. As far as suppliments, go with creatine, glutamine, multi-vitamin and whey protein. Also try posting a question in the diet and suppliment forums. If it's ok with you, I'll move this thread to the workout forum and you will get more responses.
