To confuse you even further, I would not do Korte unless you are certain your form is really good on each lift. Lots and lots of reps each week with poor form might not be a good way to go if you are relatively new to lifting. And the lighter weights in the beginning would let you get away with poor form pretty easily.
I would go in a different direction completely than fullbody. I'd go to something along the lines of BIG where you hammer the crap out of one lift a day each week. 5-3-1 would work too, I'm not sure why you think the progress would be too slow. I think Wendler himself says something like, well you're not making any progress now, so how will it hurt?
That and eat more. WHoever pointed that out is right, if you aren't eating enough you'll stall on almost any routine.

Hack away at anything which isn't essential. Do what you love, and do it often. Fazc.
Everything competes for recovery so more assistance is not always the best idea. miked96
