Absolute links, absolutely. I did otherwise early on, and learnt my lesson. Spent many hours afterwards fixing things.
if the full url contains two or three keywords, would changing root-relative links to full-absolute links increase the page KW density over the limit, and incur a filter?
Can't see that happening unless one is trying to game things already with many unncessary kw's.
The increased page size will definitely significantly lower page loading speed, to which G has become sensitive to the point of obsessive.
I don't know, man. If your code is clean, with no auto-generated bloat, it's a minor factor.
