There are quite a few threads here already discussing recommendations on rafts. You're on the right track with Aire and NRS. I just went through this, and besides those, I also looked at Vanguard, Hyside and Down River (they're local for me).
You'll find they are all good rafts, and they all have advantages and disadvantages. You'll even find differences among their different product lines. Go to all of their websites, and if you have some local stores, go there and check out as many as you can and ask the store owners a lot of questions. I also spent some time asking friends and guides.
Frames and oars will be similar, but I think you'll get a lot of votes for Cataract or Sawyer oars. PFD's are personal taste and fit mostly, just go try on as many as you can and go with feels the best - you'll be wearing it for the next 5 years...
You might check out some of the used packages that often turn up hear. You might find just what you're looking for ans save you some cash.
Gearing up is half the fun, so take your time and enjoy!
