Rayne, there are various sub-series within Discworld, although most of them include characters which appear in other series as well. All of the books are pretty much free-standing, plot-wise, although as you progress you'll see the characters grow and change.
The order you read them in depends on what you like: crime stories, go for the City Watch sequence, starting with Guards, Guard; fairy tales, go for the Lancre Witches, starting with Weird Sisters (I don't think Equal Rites is as good); metaphysics and the nature of reality, go for the Death books, starting with Mort or Reaper Man.
Tiffany Aching is most closely associated with the Lancre Witches sequence, but hers stand pretty well on their own. And they're wonderful.
Woops, here's a good reference:

I keep forgetting to bookmark that!
I just Google "discworld reading order" every time I need it. Heh.
by the end, large sections were being done by a composite creature called Terryandneil
It's possible that Terryandneil is one of my favorite authors. I found that book ridiculously and wonderfully readable.
Yeah, if you've started Wee Free, I'd keep going with Tiffany Aching, which stands alone pretty well, and then you can decide what else you want to do.
If you want to appreciate the full glory that is Granny Weatherwax--and Aunty Nogg--you'll want the witches stories, too.
My personal devotion in the Diskworld is to Ankh Morpork and the Guards. I do adore me some Sam Vimes, especially when he's playing off of Lord Vetinari.
I adore them all, but my favorites are the Death books. And the ones featuring Susan.
And the ones featuring Susan.
SUSAN! She and Tiffany are my two favorite characters.
