Replying to Special Blend pants sizing and color

So i am in the market for some new pants, as i lost my beloved predator wear pants at my cousins condo in vail. I was thinking of picking up some special blend annex pants http://www.dogfunk.com/dogfunk/SPE0354/Special-Blend-Annex-Shell-Pant-Mens.html#
in either the plum, grey & black, or the Purnk color (purnk is on the special blend site). So two questions. First: I know their stuff runs big, but im not too familiar with the sizing. I wear L pants usually, im 6'1 and like 150 (real skinny) what size would be best for me? I like baggy stuff, but not ridiculously so.
Second: What color would be best with the oakley evo jacket in ozone: Grape royal, Black and Grey, or purnk?(also considering the Green beach check splash, but doesnt look like it would work out)
Im not asking for fashion police, just any input. Thanks alot
