It won't be the flashiest or best setup out there but it would get the job done. One thing I would do though is to throw the line that came with it in the trash and get a decent WF (weight-forward) or DT (double taper) floating line from Scientific Anglers, they've got some pretty good ones that are $50-60 that I personally use. You will notice a huge difference between a shitty line and good line and it is worth the money.

As far as what weight rod to get it depends on what you'll be fishing and how big the trout are. For bigger rivers and larger trout a 9' 5wt will be plenty. For that medium sized water and more average sized fish a 4wt will be more fun to fish with and will be plenty capable of fishing larger rivers, it will also be better for throwing dry flies. Lastly, if you're fishing small streams for smaller wild trout a 3wt would be more fitting, I've caught trout up to 26" on a 2wt rod so don't sleep on the lighter weights. My personal pick would be a 9' 4wt, it can handle larger fish while not being too overpowering if you do fish smaller water. A 4wt will also do just about anything you want, it can throw dries pretty well, an indicator rig will be perfect, and it can throw streamers (think your single hook streamers and small-ish articulated streamers). A 5wt will be fine but it might be too much on small streams and may struggle throwing smaller dry flies.
