Hey there, I don't have the answers to some of your questions as I don't do heavy gaming. Here's what I can say...
1. Not sure - I have not tried.
2. Yeah.. I have 3 versions of angry birds here.. all free (had to pay on the Nook Tablet).
3. I have not look there yet (just got this tablet recently and too many other toys showed up at the same time

)
4. Plenty good enough for angry birds, pinball and crash bandicoot.
5. Absolutely yes.... lightweight, great battery life, nice shape and textured/non-slip, typing is easy, touchscreen feel/interface is deliciously smooth, etc.
6. Like a mini-Bravia!! (great!)
Good luck and have fun!
edit: ...and this giant TV remote is really fun! I started registering a few different devices but it became slow/tedious to switch selections. So I took the cable box remote page/item and customized it (added more buttons for the TV power, volume up/down , input,... followed by some commonly used buttons for the receiver

). So now they're on the same page.
