I mostly want to get rid of wheel hop and put power to the asphalt while maintaining good street handling. Naturally, I'd like to have all the suspension and driveline upgrades, but for now, on a budget, what suspension upgrade(s) would be the most bang for buck to start with, and what would be next? I'd like to keep it well under a thousand dollars to start with, and then maybe up to a thousand next year for more suspension parts.

Wheel hop is very simply a rapid and repeated loss and recovery of traction. When your car begins to accelerate various bushings and suspension/chassis components deflect. Under normal driving conditions this flexing is negligible but when the car is launched aggressively the deflection causes significant toe changes which reduce the contact patch of the rear tires. This leads to a reduction in traction and momentary wheel slippage which alleviates the toe changes and allows the rear tires to regrip. The vicious circle then continues as the suddenly improved traction again results in deflection and toe changes leading to wheel slippage.
Getting rid of wheel hop is all about limiting the movement of the rear tires in relation to the chassis under acceleration. The main culprits are the rear cradle and differential bushings, rear trailing arms and their bushings, and the toe rods and their bushings. For someone that hits the strip regularly it would be a good idea to go ahead and address the control arm bushings while everything is apart. If you have any questions feel free to hit me up.
