You don't have to get training pants, but I find it easier to have pull-up type diapers for easy ins and outs.

I will say, um, my DD's not fully potty trained yet, but she hasn't had any real issues with it (never been scared, loves to flush)...
I wouldn't get her training pants until she can pull them on and off by herself (with no help, at all, getting legs in and everything). Until then, diapers are easier for kiddos to take off, and you will have to wipe her bottom anyway... at least that's my experience.
And be prepared for her to get bored with it, possibly a few times. Right now it is new and interesting and she gets positive attn, but she may get tired of it after a few months. We kept lots of books, crayons, and a few small toys near the potty. A few times, DD has gone through spurts where she refuses to sit on her potty, and it gets frustrating. Especially when she looked at me and said, "I'm not pooping" when she clearly was... we had a big setback when we moved, but she is starting to be consistant again.
I actually just incorporated the potty into our routine, and we pretty much have stayed with it. And, of course, we never shame her or even call "accidents" by that word. DH and I just say, "oh, you peed, let's clean up."
And congrats again! It's so exciting!
My point... it sounds like you are handling this awsomely (if that is a word!). Just don't get down on yourself if it doesn't work yet. Though it just might and that would be wonderful!
ETA - I had trouble finding panties small enough for dd. The ec store (theecstore.com) has some tiny undies that may fit better than the 2T ones. The 2t Dora panites at Target are much smaller than the 2T Hello Kitty ones FWIW.

Nursed my babe, dd2 (2008) until self weaned at 3yrs. We survived a major nursing strike.
Awesome for Baby #3 who turned out to be a (Aug 2013)!
I know a little gal who was 14 months old, that only said "mama" and "dada", but her parents did sign language with her and she came up with her own sign for "dirty diaper". Her parents transitioned that from meaning "change me" to "I need the potty". She was completely PT'd by her 2nd birthday, when most children's parents are just starting to think about PTing.
As for panties that small? That's a tough one. My little niece was (and still is) TINY. Elfin. Her mom just bought the tiniest panties she could find (a snug fitting 2T) when she was PTing her at 3 years old.
I agree about the Hello Kitty undies being big at Target. The tinkerbell undies in size 2T are really small, though. They fit her at 18 mo's. Hello Kitty's still too big. Also, the Gerber training pants seem to be fairly small in 2T. And white and plain color is much softer than patterned, and my dd much prefers plain over patterned Gerbers as a result.
FWIW, my dd can't really pull down her pants on her own yet. But she does race to the bathroom and put the potty insert over the toilet. She can't get up on it on her own, so when I hear her fumbling in the toilet I go help.
My 17 month old is interested right now too. He loves to sit on the potty, goes and lays down where we change diapers when he wants changed and has lately even started taking his diaper off after he goes.
My oldest was 26 months when he was completely trained so we're taking the same approach this time.
You might want to go check out the Elimination Communication subforum (under the Diapering forum). They have some links for tiny underwear, training pants, and all that sort of thing. We haven't tried training pants yet, but I think ds is almost ready, so we're going to try soon.
