2 column layout struggles

hello all

so just as i feel i am slowly turning into an avid CSS user in which i
can get more then the basics CSS throws me a curve and buckles my knees

heres the issue...

im using the 2 column layout from glish
http://glish.com/css/9.asp

the trouble is A) how do i get the two columns to line up at the bottom? they dont make a nice line at the bottom
and if i cheat and use <br>'s they still dont?

the height 100% is what i want on both (so they both meet up with my footer perfectly, but how do i do that?

B) both columns are 2 shades of green and my body background is
gray no matter what i do i get a 2 or 3 pixel space between the two columns that shows the gray background. im using ie 6 for this and
recall reading about a bug with ie 6 but another 2 column layout i did there was no line, margins are set to zero and the left column is the float one.

if you could throw me a bone here i would appreciate it.

i can post my css if desired

thank you
