P0102 is a "bad MAF" code. P0300 is a "random misfire" code. I would recommend tracking down the cause of the misfire code first. It'll take some trouble shooting, but it could be bad spark plugs, bad coil packs, bad O2 sensor, bad fuel injector, bad EGR, or a clogged cat. These are the simple fixes, so lets just hope it's one of these. They're definitely where I would start. Plugs first, being that you can check them without spending any money.

Just be easy on it. Try to keep the RPM's low, and don't run it hard.

A random misfire may be a bad ignition coil. A multimeter is going to be your best friend on this one.

Start with the cat and 02 sensors after the plugs, though. After ten years, I wouldn't be terribly surprised.

For the maf you might try cleaning it with electrical parts cleaner before you replace it. You can get it at any auto parts store and you can use a qtip to gently clean the maf wire.
