2. The LimoStudio-Photography Photo Portrait Studio Kit – if I buy this do I still need a camera light or do these lights replace that?
Yes. You don't need both.
3. The Pro 72” Super Strong Tripod – will this work with a small point and shoot camera or do I need to buy some sort of attachment to secure my camera onto the tripod? I have a small canon digital camera that takes videos and I will probably start with that first and see how it works before purchasing the camcorder.
Does your camera have a tripod mount? This is a hole (about 0.5" wide) with screw threads. Most cameras have these. If your camera has it your are good to go!
1. The Cowboy Studio Reversible Pop Out Background – what is the size on that? Nothing on Amazon is $34.77 for this product. It must have gone up and now there is one for $48.22 (4x6) and another for $52.07 (5x7). Also, do I need to buy something to hold it up or can I lean it against a wall?
Yes. You can lean it. Bigger is better. ( Warning folding back up can be a nightmare. I have to google a video to show me how to fold it.) Depending on your wall you might need a clamp to hold it in place. I just lean mine because there's nothing on the wall.
