Run it by Autozone and have them pull the CEL code for you.
From your description, it sounds like the engine is missing. Changing the plugs/wires usually clears that up.
Get that code first and we'll go from there.

The evap leaks are something to worry about mainly b/c you're releasing gas fumes into the atmosphere.
The Evap (Evaporative Emission Control System) is made to maintain fuel tank pressure. A leak can mean a loss of pressure, and start robbing you of gas mileage, and cause abnormal engine operation due to lower fuel pressure.
The code thrown for the purge valve is one to look into. Replacing the valve, in most cases, takes an hour or so. (The Purge (P) point is a common source of evap leaks)
Have your evap system checked for leaks by using a fogger machine. It runs a harmless smoke through the evap & fuel system, and the smoke comes out through any leaking places.
It sounds as though, b/c you have a purge valve code, thats the source of both codes.
RUn a smoke test first, and if it leaks out of the purge valve, replace it then retest. Either way though, the P/V is not functioning, so it should be replaced.
If an open evap leak is present, or the purge valve is malfunctiong, the vapors could build up and excessive pressure and cause an explosion in the fuel tank.
Heres a picture of a standard evap system and the fuel vapors travelings for you:
