All genres I'd love to get to know in-depth. Here's what I've heard so far:

I don't particularly like Reggae, either. Hence the fairly low rating for London Calling.

i don't listen to a lot of punk like i used to but these were what i used to play most.

bad brains - bad brains
minor threat - complete discography
black flag - damaged
black flag - the first four years
the adolescents - the adolescents
buzzcocks - singles going steady
social distortion - mommy's little monster
cap'n jazz - analphabetapolothology
channel 3 - fear of life
choking victim - no gods, no managers
d.o.a. - hardcore 81
gorilla biscuits - s/titled
husker du - zen arcade
leftover crack - fuck world trade
mission of burma - signals, calls, and marches
rites of spring - end on end
stiff little fingers - inflammable material
wire - pink flag
the saints - (i'm) stranded

Gospel - The Moon Is a Dead World
Circle Takes the Square - As the Roots Undo

You absolutely must listen to these if you like pageninetynine and Converge. Also, if you like those, check out the screamo albums from my rec thread.

I got a lot of good recs from this list here:

And for punnk, since you're a metal head, I highly recommend The Age of Quarrel by Cro-Mags.

The Descendants' "Milo Goes to College" is an absolute gem of punk rock.

Yes it is. Everything Sucks is fun, too, if less endearingly raw.
