I got the tension issue all sorted out. Turns out there were two different threads wrapped around the back of the bobbin race thingy. Of course, by the time I discovered that, it was already taken apart, so I went ahead and cleaned and oiled her up, put her back together and did some test sewing and perfect stitches with beautiful tension were the result! I KNEW, as soon as I saw those threads that I found my problem. :D
Thank you all for the warm welcome for my new baby. :D I'm pretty excited about her.
