I think in order to determine the best option you (and your friend) will need to decide what type of salmon fishing you intend to do. Will this set-up be primarily used for float fishing the Vedder for fall salmon in flowing water (i.e. water with any type of flow)? If so, I would recommend a 10'6" float rod (Trophy, Shimano, Fenwick, and similar brands offer decent rods at the $100 - 150 range) with a decent levelwind reel (e.g. Abu Garcia C3 5500 or 6500). This set-up will last a lifetime if taken care of, and will provide for plenty of learning for your friend to master. It will also be much more efficient for float fishing than a spinning set-up for flowing water (e.g. drifting roe).
If you intend to primarily fish frog water and deep pools with little to no flow, using lures and jigs for example, then a 9 ft spinning rod and spinning reel would be the way to go. This set-up will be much more efficient for this type of water over a level wind set-up.
I would lean toward the levelwind set-up, as I believe float/drift fishing medium sized rivers like the Vedder will be the most common and accessible method for your friend. But that's just my gut feeling.
Good luck and have fun!
EDIT - Oh, I forgot to mention fly fishing! A fly set-up will allow you to efficiently fish both methods, and under certain conditions is the best method to use! This is the set-up I started with and used for several years before obtaining my first gear set-up...
In all seriousness, IF your friend takes to fishing and really enjoys doing it, then they will eventually end up with more than one set-up for sure. In other words - there is NO ONE ROD TO RULE THEM ALL!!!
