On the way home I noticed my needle going up. It would go up on acceleration just a tad then settle back down. A little closer to home it went up to 2 lines before the red. I turned te A.C. off and it went back down.
Got home and let it idle, the needle climbed up and I turned it off. I let her cool a little then turned it back on with the heater on full heat, but no heat coming out?
It appears that my fan clutch is the heating issue, but what about no heat coming out of my vents?

Well coolant level low, added about a gallon and a half and no more overheating. But I know I have not resolved the issue as why was the coolant low...maybe the fan clutch is not working as it should (loose) which caused some overheating with water bubbling out over time thru the reservoir?
Still can't figure out why no heat blowing?

take your car to a radiator shop not a gas station or one of these fast lube places. A radiator shop can check to see if the tubes of the radiator are clogged and if the inside heater core is also plugged. If the system is clean there is a hose assembly on the passengers side that operates the heater make sure it is working. The radiator tech will probably know where to find it. If you haven't had the radiator flushed in a few years have the radiator back flush the whole system including the heater core I hope this helps. You can also have a bad fan clutch as you said but I have found most peope never think of back flushing the system which any good radiator shop can do. The dealer is very expensive for an older lexus. Remember to flush the radiator every 2 years I recommend do it at christmas it's a slow time for most radiator shops and this will help you remember to give your car a christmas present.

your water pump may be leaking. that's why you were low on coolant. you dont' have heat because you need to bleed the system after adding coolant. see the big bolt right on top of the thermostat housing? take that off: it's TIGHT. top up the coolant, until coolant comes out the hole. replace the bolt. run car at about 2200 rpm with the heat on full. after you get to normal temp, you should have heat. if you don't, your water pump may not be flowing enough.
