have someone pull on the release handle while someone else is pulling/wiggle the e-brake cable at the rear by the wheels to see if they will release. you can try spraying penetrating fluid on the cables and wiggle trying to free them up. if not then they may have to be cut and freed up so the rear brakes are not locked on.

There is a difference in the LS and GS, as well as different years.

There is an out fit the mechanics put on to reset the codes in the car computer. If you want to try yourself try taking the battery cables off the battery for an hour but if you do that then every thing has to reset itself most of the time even your radio. I really don't recomend it.

The noise might be coming from a belt, tensioner, alternator, idler pulley or a pump. Valve body gaskets, drain plugs, and other parts have gaskets. They might leak over time, and will need to be replaced. Sometimes bolts get loose, and then the gaskets leak.
