Bleeder....is that where i am going to hook up my manual boost controller?

Yes, normally the hose would go to the electrical wastegate solenoid located on the pass side valve cover. Since you will not be using the electrical WS with a pressure source, just take the hose off, and leave the original wiring on the solenoid connected.
Do you want a picture of how you will route it on the car, i have a few spare parts and could set it up in a few minutes.

I don't have one myself, but if you ordered a grainger valve from RJC I don't believe it should be hooked up the same way K.C. had his bleeder valve set up. If you look at the pic and read the link from their site, their "Hybrid Boost Controller" is connected between the turbo compressor and the WG actuator. In their pic you can see it is connected right next to the compressor vacuum line fitting.

I'm no expert and I'm still learning too, but the way I understand things is a bleeder valve protects from overboost by bleeding off excess boost pressure beyond whatever level you have it set at. A grainger valve "contains" the pressure coming from the compressor, thereby keeping the WG closed until the set boost is reached, then it opens allowing pressure to the WG actuator. After the grainger is open the WG actuator protects against overboost like it normally does. Keeping the signal pressure away from the actuator aids in spool-up. Some people use both a grainger for spoolup and a bleeder for boost control.

Again, this is just the way I understand these things. Just trying to help.

GRAINGER VALVE- www.grainger.com Grainger Item: 4A789
This is a grainger valve, this isnt the correct one, but its what everyone refers to as a grainger valve.
IT bleeds air off to Raise boost, it doesnt protect anything, it just raises the boost- The factory solenoid is whats supposed to PROTECT boost control, it pulses to control boost level even thou the ecm doesnt know where the boost is at. If the car knocks, it will pull boost and timing.
RJC goes inline, it vents, its also a ball and spring.

The more air pressure to the wastegate diapragm the least amount of boost, hence if you blow a line off the compressor or wastegate, instant 30psi
