Installing a fuel pressure regulator

[moponys]

I think I need to get a fuel pressure regulator. I have 24lbs injectors and 190lph fuel pump and think I need to boost up the stock pressure to around 40psi. I have three questions:

Are they easy to install(come with directions or is it so easy you don't need them)and which type should I get?

Do I need to buy a fuel pressure gauge too or is there something on the regulator that tells me what it's set too?

Once I install the regulator, I was going to probably bump up the timing to about 16 degrees. Will the Octane I use need to be 93 or higher or is 92 enough? If 92 is not enough, is it okay to put octane boost into your tank at every fill up?

Thanks in advance!!!

I want to do this next friday and go to the track for the first time later that night.
