Welcome to the forum SlikSak!
Let me start by pointing you at this thread on the Cobra 29: 50 watt Cobra 29 review from FGBest. That will give you some ideas on the mods available.
Range depends a lot on conditions, terrain, etc., but I'm guessing that you shouldn't have any problem talking 40 miles with 450 watts unless the terrain is just too hilly or obstructed. The problem will be if you can HEAR stations that far away.
There are a lot of good antennas out there. It might be a good idea if you give us your vehicle type and any special considerations to help you pick something. A simple answer is that a plain 'ole 102" whip on a spring works really well.
