what is truly important about ports, is it the area of the port, or the length or what?

all of the above. add box volume and desired frequnecy up there too.

ok...i checked out the port calculator in your sig...
one more ?...im not sure i am doing the cross sectional port area deal right...is that the port width x port height, or is that wrong?

area = wXh

does it matter, for a slot port, where you make the "L" at, or could you have like 2" then the "L", and then the other 30" after that?

the L is what you use to determine the port tuning... The port area is the Width and height of the port.

jl says tune to 32 hz...what "L" should i use?

Depends on your port area and box size...

1.75 cubes, and 24 square inches

thats what i got, but i mean where do i turn the corner for that "L". like say i have it going straight for 8" then turn for 24"...is that the same as straight for 24" and then turn for the other 8"

I don't catch ya.
For bends, measure the port length at the middle of the port. Also, if you use a side of the box as one port wall, then subtract 1/2 of the port width from the port length for end correction.

thats what i was asking...are those two ports going to create the same frequency?
