it seems like some of the tips have helped a bit (or the added weight did the trick?)
I'm pretty certain the extra weight helped you. I routinely use 1-2kg more weight in the winter than in the summer, to accommodate a little more air in my suit. It's not the undergarments that keep you warm, it's the air. The undergarments just keep the air in place
I am thinking about getting a set of Aclima woolnet shirts and pants as suggested here (and by several others). I don't know if I can use this in the summer or warmer places as the red sea etc. or if I will hav eto buy something like the coolwool too.
I sugget you try the woolnet before buying more undergarments. If you're planning on getting a bit damp from sweat, the mesh construction is vastly superior to anything "whole cloth" so to speak. A non-textured textile will often stick to your skin when damp, while the mesh provides breathing space for the skin. If the wool gets too warm, I'd rather consider mesh polypro than a non-textured textile.

Btw. I am using the artic socks from fourth element. Any suggestions what to add to that for warmer feet
Just one: Whetever you do,
don't use too thick socks. If your boots are too tight, you'll restrict circulation and you
will be cold. So, if the choice is between newfangled, "technical" super-duper-miracle socks that doesn't let you wiggle your toes, and some thinner, plain woll socks that don't give your feet enough space, go for the latter. If I lace my rockboots just tight enough, my feet are usually fine, if I lace them just a little too tight, they'll be cold. With the same socks, in the same water temperatures.

My only concern is that with the added undergarmens and baselayer I will have to use even more weight and it already feels like a bad joke (but I suppose singles and drysuit in cold water needs a lot of weight.)
Heh. I did a dive outside Hitra early March this year. Neoprene DS, Woolnet + Woolpower 200g all over, an extra thin wool vest (an old Dovre undershirt I'd cut off the arms from) and the previously mentioned foam pad on my chest. -5C air, 3C water, small, open boat. I was toasty warm, but even with winter weights I had to duck dive to get down and hold on to kelp stipes to keep from corking when shallower than 5M...
