this weekend i hope to get my engine in few things

FOR FIRST TIME START UP
1.on turbo side if i open wastegate fully the car should run no boost is this correct.
2.i am using 2.5mm de comp plate can i actually start the engine up on std zetec managemnt to check for leaks etc just not drive or rev it just sit at idle.
3.should i just set timing up as standard untill car gets set up.
4.ayn other things that i should look ot for exept from leaks when i start up for first time
ANY COMMENTS WOULD HELP ALOT THANKS TOMMY
