Given that you're trying to work within a limited budget I would suggest a .030" kit being that this is the most popular oversize and as such the parts are mass produced keeping cost down.
For pistons I would go with a flat top with the valve reliefs also in interest of cost.
For bearings, assuming your crank is good you would probably be able to go .010" under on rods and mains with no issues and parts are again readily available.
For the cam I would stick with something that is fairly mild and the Isky cam you mentioned would probably do well... I think that you will find most of the money is tied up in the heads and machine shop labor.

Northern auto parts does offer a nice rebuild kit with nearly all the parts you would need at a good cost. There is no need for expensive forged pistons for what you're trying to accomplish.
