the color cast can be caused my several things, 99% of the time the lighting used. If you mix lights (room lights and flash for example) you may get a color cast.
that is the explanation of these color differences - different shutter times allowed different amounts of incandescent room light to alter the color
You can adjust for that in PS or whatever you edit with. Set White Point is what you are after on a color adjustment menu. sorry i can't be more specific on that, but others here can. (many will tell you to shoot RAW, but too late now, right?)
The background...you can select it and erase it or replace it, etc. How to get it to look natural is a bit harder. Here is recent attempt by me - studio shot of the kids, the BG was something i had lying about on my hardrive..not too bad, but could be better. Does not look real to me, but does look the BG's i have in some of the JCPenny/Sears?etc portrait studio shots of my kids.
I could put some gaussian blur to it and that might help.
If you have a pic or can get someone to email you one of a BG paper, or you can generate soemthing like that in PS, etc. Just paint yourself one! Possible scan a portrait, and copy and paste and dupe the BG until you have enough of it.
