The TFO rods have a lifetime guarantee. Pretty tough to beat and definitely not available from Cabelas. I have a TFO and have no issues with the finish. I do know that if I did have an issue, finish or otherwise, that I can get it fixed no questions asked.

As for reels, I have a preference for the tetons. Here is the thing with a reel for a 3wt though...it just holds your line (like you mentioned). Given a choice, I would spend less on a reel and more on a rod for a 3wt. If you do consider a Cabelas combo, I would also account for new line. The stuff that came with the cabelas combo a few years back was terrible. This may have changed though...

Waders. I think your spot on. If you are only getting out a few times a year its just not worth the cash.
