I would try vga=794 first. The difference is that 775 should give you a
1280x1024 x 256 color depth while 794 will give you 1280x1024 x 65k
colors.
The GRUB_GFXMODE=1280x1024 is the way to go now but when I use it I get
slow screen writes whereas vga=794 seems to work well here. I don't
know why that is I'll need to figure it out soon I think.
I got these vga modes from..

Not that I know of, just keep trying till it works the way you want it

If you run dkpg-reconfigure console-setup and go through and don't make
any changes you can see what font and size you have now.
There may be a command to query what your console setup is, but I don't
know.
