Welcome back to fishing!
A 5wt is great choice for a rod to start with, and will get the job done in many fishing situations here in Alberta! As far as set-ups/rod and reel combos go, the Orvis Encounter series or Clearwater series, at around $159, is good quality for a good price. Temple Fork's NXT series is also good, as well as Redington's Crosswater outfit ($140). I think Bass Pro has a starter outfit as well, but I would go with an outfit from a more well-known, respected fly fishing company.
Hope this helps and let me know if you need any more information!
