I, too, use WN as my primary airline. As far as hotels go, you can always "double dip" as a member of Hilton Hhonors. They give you 1/2 credit on WN in addition to the hotel points that you earn. If you are trying to continue to earn free tix with WN, remember that their points expire after one yr -- not that commom of a restriction on major airlines.

In addition to whatever else you choose to do, I have seen it recommended elsewhere on this site, that you get the Starwood AmEx card. You use this card to earn points towards free nights at *wood hotels, but you can also transfer miles to almost any airline. Further, if you transfer in increments of 20,000, you get a 5,000 point bonus. This is another pretty good deal for someone who does not travel all that often, as it allows you to continue to earn points/miles even when you are not travelling.
