Good to hear about the ten gallon.
I still have my 75 gallon under a single T8 bulb. It's only about one inch shorter than the 37 and everything still grows like crazy. Stick with low to medium light plants (arranged appropriately) and all should work fine. Color temp is really not the issue (unless you like the look of 6500k, I personally prefer about 8000k). Same as the ten gallon, look for a "full spectrum daylight" bulb somewhere in the 3000-10000k range.
As for brands... They are all about the same unless you get into the really low quality (generic no-name brands) or very high quality (ATI, Giesemann, etc) stuff.
I support the right to arm bears.
