Hey everyone, I'm just about ready to begin construction of my cab. I thought it would be good to post my plans and maybe get some feedback BEFORE I start making cuts

Here is a link to the Sketchup model I made for it:

I used LuCiD's cab as a starter and modified it a bit (angled front and dimensions mainly). The panel dimensions are shown in the image below, as are the specs for the entire cabinet. I do have some questions about the construction of the cab:
1. I'm planning on using 3/4" AC plywood because its cheap, light and strong. My only concern with it is that it may not paint well? Anyone gone this route and have an opinion on it? I'd like a nice black cab and don't want to see grain/roughness in it. If AC plywood won't cut it, I may splurge for MDO or cover it with vinyl/laminate.
2. Do I use screws, glue or both to attach everything? Are L-Brackets viable? Then I wouldn't have to drill through the outside panels.
3. I have almost zero shop experience. That being said, would it be worth having Lowes or Home Depot make some of the longer cuts on the plywood for me? And for routing, for someone with no experience, is it easiest to route the edges before you construct the cab?
4. Anyone for or against the following:
* Casters on the bottom
* Door on the rear to allow me to remove the TV if necessary
Thanks for the help and wish me luck!
