You have the common symptoms of a failing ignition switch/harness assembly. It's a fairly common issue with the GM W-bodies. You may want to double check all your battery cable connections to be safe, and have the charging system checked (Auto-Zone and Advance do it for free).

Here is a link to the repair proceedure if you want to tackle it yourself. Thanks bnaylor (and GTP dad) for the tips and maintenance section at the top of the Grand Prix forum
