My question involves bankruptcy in the state of: NY

I filed for BK Chapter 13 in 2009 with a 100% payback plan. Not all the creditors filed a claim. Now, I only owe about $ 9,500.00. I would like to pay off my BK Chapter 13. I just have a few question and I would appreciate some help.

1. Can I pay it off since I am in a 100% pay back plan?
2. If I pay it off, will the creditors who did not file a claim be entitled to get paid too?
3. I am planning to use my $ 5,000.00 tax refund plus $ 4,500.00 401k Loan. Can I do that?

Thank you.
