Eng/fuel layout set up

[ripdog28]

So after reading all kinds of others layouts i am at the point in the build to start getting it mocked up.
I am stuck between an Electrical and Mechanical fuel pump. I will be doing more street then track. But I will also add a 150-200 shot (the eng will handle it) and I assume that electrical is the way to go. Will a mechanical hold up and be easier?
How many Psi do I need in a pump? How do I get more fuel when I hit the button so I dont starve it?
What style fuel return should I run?
Rubber or tube fuel lines?

I am looking at low 11s street and low 10s on the juice. My sig will give you my eng specs.

Pics of your set up with a description would help.
