IMHO, it does matter where your gauges read. As has been stated, you'll get an idea where "normal" is at when everything is functional. Then, you just have to keep it there. The gauges help tell you what state you're engine is in... and that's important. Me, I taught my kids to look at gauges about every 5 minutes as they drive. If you can catch a problem early, it avoids expensive repairs later. Put out the smoke and there's no need to put out the fire.
In this case, did you make sure there's no air bubble in the engine, and it's full of coolant? Me, I pour coolant into the thermostat hole in the block and then install the thermostat. I make sure the thermostat has a burp hole in it's rim t bleed off any trapped air. I usually have cut the heater hoses and installed a back flush kit. That way, at any time I can burp the system by loosening the hose bib cap on the back flush kit.
When all's said and done, if you can't trust your gauges, fix them till you can. If you don't have schematics for the gauges, let us know, and you'll likely get a set by the end of the day via email from someone. It is not hard, and you'll be doing yourself and your Jeep a favor. It just isn't a good idea to drive blind. They don't call them "idiot lights" for nothing....
