I really think Pull-Ups are only good for the nighttime when pottry training and not for during the day...they are just too much like diapers. Anyway...Here's what I wrote previously to another mom with Potty training questions:
I'm a big believer in this potty training tip: Once you start, don't go back!!! There is nothing worse than going back and forth between panties and diapers. And, once you've started, commit to it whole-heartedly....forget about yourself and what you want to do for a good week or 2 and focus on the potty training.
Here's what I do...take her to the store and have her help you pick out specail underwear (like any characters she's into, princesses, etc.) Then put her in them! I ask her every 30 minutes or so if she needs to go to the potty OR you can just say, "Let's go to the potty!". If she goes or even if she wets her pants, note the time and how long it is until the next time she goes. You'll kind of get a feel for her "schedule"....of course this can be affected by how much liquid she takes in, but in general you'll be able to figure it out. Once I'm familiar with the time, I'll even set a timer to remind myself to ask her/tell her to go to the potty.
When she does go in the potty, I give tons of praise and then a reward...a sticker on a chart, a small candy or snack, a book she wants to read, or I even let her watch a special Potty Movie (my kids loved "It's Potty Time" even though I think it's extremely annoying, but it worked!).
When she messes up, try really really hard NOT to make a big deal of it!...this one is really hard for me, cuz it can be soooo frustrating! It is also discouraging to her and then she'll start to hide her messes or be afraid to tell you, etc. So, when she messes up, just say..."oh well, maybe next time!" or "remember to always tell me so that I can help you" or similar things....and give hugs.
Potty training can be long and tedious....just DON'T GIVE UP!!! So many of my friends would say, "just give up, it's not worth it, diapers are easier, just wait till they are 3, etc." But, I literally couldn't afford to! Besides if you give up, your child will get so confused and it will be harder and harder to try again.
So, be committed and you'll do great! Good luck!
