Between 15 and 30 miles per hour
SOURCE: Won't go past 40 miles per hour
no not muffler problem could be bad gas or TPS sensor how many miles you have on it?
SOURCE: 2002 jeep liberty siren whining noise on start up
I had the same problem at about the same mileage. Replaced the power steering pump and the start up screaming went away! ( The Jeep's and mine!)
SOURCE: oil pressure gage
At idle, at operating temp is there any ticking from top end of engine? Are there any knocking noises brom bottom end?
If no noises, change oil and add some Marvel oil to clean out galleys. If that dosent work, change oil pressure sendingf unit. Also, if you have a mechanical oil pressure gauge, hook it up and take a direct reading. Oil pressure (in any vehicle) at idle should NEVER be less than 15psi. Generally in 4.0 jeep engines it's never less than 30, with a high reading at driving rpm of about 40-60! (but, you did not mention what engine you have)
SOURCE: whining noise
Could be a few things:
Belt slipping- adjusted through tensioning bolt on bottom of power steering pump
Pulleys- take off belt and hand turn pulleys. Find one that gives resistance and possible makes the whining noise. It's probably the idler pulley.

Check wheel balance,
check steering linkages for loosness - such as tie rod ends, steering rack linkages etc,
check driveline for worn/loose joints and bearings.
