I don't understand why people on this site are so adverse to working on their own cars. MMM builds freaking houses! A car is small potatoes comparatively, since they're DESIGNED to be taken apart. If you had a leaking toilet, and the plumber quoted you $1500 to replace it, would you just do it? Hell no, you'd research to see if it can be done cheaper.
Struts are easy to do, and fairly cheap. I put high end shocks and struts (Bilsteins) on a BMW, and it cost me under $700, and that's with new rubber mounts and strut bearings. How did I do it so cheap? I didn't pay a mechanic to do it. I would be really surprised if you couldn't get a set of replacement shocks (KYB is a good brand that's fairly inexpensive) for under $400.
You then take yourself over to Youtube and figure out how to do the replacement.
For tires, get a set of Michelin Defenders that will last 90,000 miles, then don't worry about it anymore. They'll probably dry-rot before they wear through the tread. They shouldn't be more than ~$100-$120/tire, since the Prius uses itty bitty doughnut wheels.
