Was there a problem with oil pressure prior to this happening? If not, jump it. If you hear a knocking or ticking in the engine, shut it down. Keep an eye on the oil pressure gauge to make sure it's getting pressure.
Chances are the battery needs replaced. I would also get the oil changed. If it's the 4.0L, the oil filter points straight down on the engine near the oil pan (passanger side). It is an easy one to do. Drain the oil, replace the drain plug, remove the filter, place a thin film of oil on the new oil filter's gasket and replace it as tight as you can by hand then 1/4 turn with a filter wrench.
It will take about 15 minutes to do. I would also get a new dip stick ASAP so you know the level. I believe the 4.0 holds 5 quarts. I would start at 4.5 and then add the other quart if it isn't full. But again, you need to get a dip stick.
