Awesome! I'll be bottling tomorrow and brewing Sat. Good times.
Don't shoot high. Just dial in your mash temp. Now, your HLT may read higher, but that is where your flow rate comes in. When I'm recirculating full speed, my HLT is 10 degrees hotter. The mash, however, is spot on. Dial down the speed and the temps will be closer.
Speaking of tinkering, the starter probe takes some love and affection. Keep a long screw driver handy when your brewing in case you need to move the probe back over a burner hole. Eventually the thing will find its mark and you'll be all set.
Here are some closer shots of the temp and burner probes...
