I messed up, any ideas?

[Dirty Psyclops]

So I recently “Bought” an 1994 80 series with an 1FzFe from my father. He didn't do much maintenance on it ,so i’m doing my best to tune it up and replace what I can. Part of this process I replaced the following over the weekend.
-Valve cover gasket
- spark plug tube gaskets (+plugs,wires)
- Pcv valve (+ grommet,Hoses)
- Dizzy cap, O ring, and gasket
- Reseal Half Moon
Afterwards I had a terrible Vacuum leak which I chased down to the Throttle body having a crimped gasket which I Fixed. Its now running smooth but the idle is terribly low around 400-450. I messed with the Dizzy to advance it and it helped but not much. Any ideas? 292k Miles
