Happy Birthday! You will love your new gift! I have the 2010Q which is basically the same machine plus a small pre-tensioner. It has the greatest "potted" motor and is strong enough to sew through anything. It's my workhorse. I even did my quilting on it before I bought the Juki longarm table model. Have fun!
For the UTI you need antibiotics, but in the mean time flood yourself with cranberry juice! Something about cranberry really helps. And avoid eating sugar.
