There's not really a standard baseline alignment for solo vees. There are so many variables in the springs and shocks and leading/trailing arms that it's very car specific.
The following is my opinion, so others (probably faster than me) may have better advice.
There are some basic guidelines. Put as much negative camber in the front wheels as possible. This is done with shims. I believe your car has this already. I read on this forum a while ago about changing the mounting angle of the front beam. Search for that and read up on it, but I would worry about that last.
I've heard some drivers use toe-in, some use toe-out, just keep away from anything radical (1/8" max). Mine is close to zero, and my handling is fairly neutral.
The rear alignment is more adjustable. The previous 2 owners of your car used lots of negative camber, and I always thought it was too much. They almost always beat me, so they must have cheated in some way
I really don't know what camber is best, but remember that the zero roll will keep the camber mostly constant in the turns, and too much camber will cause spinning tires on accelleration, more throttle oversteer, and uneven tire wear. 1 or 2 degrees should be fine.
Rear toe will make the biggest difference. My car was oversteering at random times, then I found out there was some rear toe out. I made it zero, and now it's neutral.
Again, it's mosty car dependent, and will depend on your driving style. If you want to start from scratch, adjust everything to zero except the front camber. Otherwise, make small adjustments and test drive afterwards.
