hi and welcome!
You can try what is called a GW letter on the BestBuy card unless it is due to drop off very soon, which I don't think it is.
Keep your loans paid up without fail.
Get all 3 CRs cleaned up as much as you can over the next few months, then carefuly pick a credit card that you can get approved on with a decent enough limit, and that works for you. Good mix of credit is good for your scores.
The FAQ link is fabulous, please read it and go back to it as necessary. Feel free to post more questions though of course.
