It really depends on how different the new box is, some aftermarket steering setups come with a frame reinforcement kit but yes it can cause extra stress on the frame. As for the tires, again it just depends on how big your stock tires are and how big you plan on going. A small jump for instance will not hurt anything mechanically but it can cause your speedometer to be off by 2 or 3 MPH. The larger the tire the more you can damage such as the transmission and 4WD system (if equipped). I know personally how fun and addicting it can be to start upgrading your ride but if you don't do it right then you will end up hurting your vehicle. Getting a new steering box and pitman arms and having them adjusted properly will make the handling a lot better and is much less trouble then modifying the stock steering system.
