Have fun up at Grundy. Been there four times, and, always enjoyed it. If you haven't fished it before try Gurd lake, tons of small pike, as well as some decent bass.
As for the combos, stick with the names you mentioned. For the type and amount of fishing you are talking about, you'll be fine. One thing with some of the cheaper combos, if they come with line...replace it with something decent.
Good luck, and, have a great time!!
