I generally use the Ubuntu patched LCD packages via AUR and this page was very helpful in helping me get it set up. I've heard the Infinality patchset is really good too but I haven't tried it yet.

Personally speaking, since I am so xterm oriented, the best thing I did was install the bitmap font Tamsyn, which I just adore. Easy to read and use. It is available from AUR, but I just download it to a directory in my home folder and use xset to add it to my fontpath.

(And Arch's wiki has an incredible wealth of information. It is one of my favorite online resources, along with OpenBSD's FAQ.)
