1st pic top right I think thats for the BOV, the middle is a coolant line that goes throught the throttle body and I don't rem what that little one is.
2nd pic that's the Idle air should go the intercooler pipe on the throttle body.

yea that little blue capped off guy under the throttle goes to the standard carbon cannister purge system...its oviously removed/ not there so its fine to have it blocked...the coolant hose is for the throtlle body like he said and the red capped one is normally for BOV..and that bottom one can either be for standard MAP sensor or boost gauge normally
