Intentionally create a vacuum leak and see what happens, it's all about mixture and airflow. I am pretty sure the dashpot is there to keep the throttle plate from snapping closed, it slows it down to ease it back to idle.

When i pull a vacuum line the idle goes down, if I put my finger over it to plug it it idles high again. I don't understand why. I am really starting to think that the valve in the throttle body is stuck open, I'm going to plug off the inlet to it and see if it idles down after it warms up.

If you verified that your brake booster is causing a vacuum leak why not replace it? if you put all of the adjustments back to proper settings and give the ECM time to relearn how your engine runs you may not have any more issues. One thing at a time us usually the best way to fix anything and with the booster fixed you will be able to test drive it with good braking and no vacuum leak.
