Do you know how old the battery is?

Hard starting may be related to a fading battery. With all the computerized controls in the WJ, a fading battery will also have an impact on the way the engine runs.

The battery seems fine. When I say hard starting I mean it rolls over great but takes a few turns to fire. I'd like it to fire up within 1 or 2 revolutions. Is this too much to ask for?
Another possibility is fuel filter/fuel pump not keeping fuel line pressurized. There are valves in both that are supposed to do that. I hope it's not the fuel pump, since it's on top of the gas tank and not a lot of fun to replace.

Try this: Turn the key to activate accessories, hold it there for 10 seconds, then go the rest of the way to start. See if it fires right up. The 10 second pause allows the pump to repressurize the fuel line.

I took my '99 to the dealer over a year ago for long cranking problem. They did a fuel pressure test, suggested replacement of the fuel pump, which I declined. Strange thing is I haven't had a problem since then.
