Secureboot by default on most systems will only boot code signed by
Microsoft.  Debian obviously isn't distributing code signed by Microsoft
so secureboot won't work with it.

I haven't tried UEFI cd boot myself yet, but I think it uses grub, which
certainly can give that error.  If it boots past that, then I wouldn't
worry about it.

Windows's storage manage will allow you to shrink the disk (although
only if it doesn't require moving files I believe).  Don't create new
partitions from windows though, just leave unppartitioned space.

UEFI boot places the boot code in the boot partition and is then
controlled by the UEFI boot manager as far as I know (I have not tried
it myself yet).  If UEFI boot works, then it makes sense to use it,
given future machines are likely to drop lagacy boot support eventually,
so if you use UEFI now, it would be easy to moee the drive to a new
machine later (although windows wouldn't like it of course).

Not that I can think of.
