Bad Alternator?

[wonton]

My dome lights and aftermarket stereo is not turning on, but everything else works like sunroof, windows, and headlights. When i start the rig, it starts fine but shortly after it starts, there is a noticeable stutter and drop in RPM then idles fine.

Is my alternator going bad?

Pretty much all auto parts stores will test it for FREE, but did you already check all fuses and relays?

That does not sound like symptoms of a bad alternator. As already mentioned, I would start checking fuses.
