No, see below.

Yes, but it might save you some ANDs. And you could disable 
completely invisible object halves by making that player black. 
Then 8 pixel should be enough.

I meant a *visible* window border that masks the objects and 
doesn't reduce the size at all.

If you comment the important parts... ;-)

I still see no technical reason, why you can't show objects 
that startt before the top. You can setup all variables outside 
the kernel. 
Where is the problem? Has it something to do with the sorting 

Have fun!
