Medium rod should be fine. I typically use slightly heavier get, but not really necessary. Might want to up the line to 10 lb braid or flouro if you have lighter line on you reel. I typically use the same tackle I use for smaller lake trout, but it's really overkill.
Only exception would be if you plan to fish in the middle of a boulder field area. These fish will bury you in the rocks if you let them run, so make sure you can horse them in if you're fishing over that kind of structure.
