Just a quick question about replacing an oil sender in my 4.0L 90 cherokee i was wondering if i could take it out and not worry about any oil draining out while i do this?

you will loose a little bit, but not much have a pan under and you'll be fine

You should lose a few drops, but that's about it. All the oil is in the sump while you're working, except for what's "trapped" in the oil galleys as an engine primer.
No reason to worry about oil loss, but no reason to take your time, either. Have the other sensor handy, and get it in the hole within a minute or so so you don't risk losing your oil priming...

should i use teflon tape or does it need to be grounded. my 90 is a 1 wire to the sender system but my buddies 01 is a 3 wire system can i use teflon on both?

If it's a one-wire sensor, it wants a case ground. I might use a little RTV Copper if I have it handy, but that's about it. Teflon could end up insulating the threads, and it's a pain to get out of the hole once you get it in there...
Pipe threads are supposed to be "self-sealing," and you can usually get the sensor to seal without adding anything. I think I usually go "finger-tight + 1/2 turn" on the sensor.
