Ouch! I had a similar experinece in the hospital with nurses trying to shove DS onto my nipples then squeezing really hard. Brought tears to my eyes and didn't help one bit - very offputting .
I thought my breasts were crap too, but they turned out to work pretty well and did the job they were designed for (& are still 'working' after 14 months). They just needed a bit of help! (And, if it makes you feel any better -they seem to have got smaller since breastfeeding so tops look far more flattering these days, yay!]
My DS couldn't latch on at all but, with guidance from the lactation consultant, we ended up BF succesfully but did have to use a nipple shield. Without it, I doubt we'd have managed. They can be a lifesaver but please don't use one without proper advice as I think they can interfere with milk supply and can be a pain to wean from (took DS 5 months. Grrr)
I wouldn't worry too much about milk not coming in yet. It can take about 5 days - you'll know when it arrives! Sounds like it's on its way now.
Can you pump for a couple of minutes to help draw out your nipples then try latching the baby on?
Is the baby sucking at all? Is she trying to latch on? If the baby wants to latch on but isn't sucking, you can stroke along the jaw or gently tickly the crown of the head to stimulate sucking.

Keep at it- it sounds as though you're doing really well.
Oh, and Congratulations
