You got it.
Use a normal 12oz can of R134a with a refill kit that has a pressure gauge.
It is critical to not overcharge the system. I doubt a "top off kit" has
enough to do that but a full can might. Follow the instructions with the
recharge kit.
You want to be very careful not to overcharge. R134a systems are not as
forgiving as the R12 systems were.
This is a basic guide with video.

The "correct" way to recharge a 134a system is with a recovery/recharge
machine. But those are mainly for shops.

Doug,
The correct (without quotes!) way to recharge a R134a system, is to put the
correct amount of refrigerant into it. You can do this with a recovery
station, with a kitchen scale or by emptying the correct size can into the
system after evacuation. The amount of refrigerant is more important than
the selection of tools. The point is that you can't get it right, using
just high and low side pressure gauges. "Topping off" a system that has
leaked down enough to stop working is a hit or miss proposition. But with
R134a cans and recharge kits readily and cheaply available, many people will
try it.
A recovery station from www.acsource.com costs $750. I find this almost
within the do it yourself budget. Basically, this is a fancy transfer pump.

Re: 1998 Cherokee XJ Air Con Problem
Doug,
Once again, thanks.
Final question I hope, just want to check that I have used the correct
valve to fill the system from as I now see that there are two. I used
the one near the top by the accumulator, not the one by the compressor,
was this correct?
Thanks

Yes.
The connectors by the compressor is called the "high side" and the one you
used is called the "low side" or "suction side" connector.
Besides, they are different fittings so the fill kit shouldn't be able
to connect there anyway.
