The kit will work fine. Why would you want to go to a PP elevator? The Y system they have already installed is really a pretty good system and very strong. When I mentioned the PP rudder it was just something I noticed that if it was a plane for myself I would maybe change. The maybe is because sometimes changing something in an ARF is more work then I would bother with because of the lack of return on my time. The last time I did a PP elevator was on a scale Tiger Moth and they aren't a lot of fun to install or set up, the added servo is often a pain to find a good place to mount on a smaller plane and added weight. The second one I built I just went with a Y. If you want to make a plane with a lot of changes then you may want to buy something like the GP Extra kit and build it the way you want it. For now you may want to just assemble this ARF to the plans, fly it and enjoy yourself while you build yourself a plane with all the trick stuff and mods. Just a thought. There are some good threads on building different kits over in the kit building forum you may want to look at just to give you some idea of what some of the other guys are doing and any problems or mods. Kits aren't hard to build and it could open up a complete new world of fun for you.
