Right now I have my suspension adjusted where the back is about a finger space higher than the front, should I leave it like that (stock the back is a little higher) or should I make it more level

I like my cars to be a little more on the level side vs having a noticeable rake.

Generally lower is better due to center of gravity. but not always. Better handleing is a relative term in regards to driver preference. What I may like in a car for handleing you may not be able to control and vice versa. Set it up to where you are comfortable with how it drives.

Finding the "best ride height for handling", which implies "best for you" will ultimately come down to a test and tune session where you try different settings to see what works best for you. Some SCCA regions put on test and tune sessions setting up several different kinds of corners/maneuvers that are similar to very short autocrosses. Offhand, that would be your best and safest bet.

The amount lowered, whether you have altered the car's OE geometry (such as with LCA relo brackets or tall ball joints), and probably even your damper settings also figure into this.

It'll help a lot if you have a good idea what specific aspects of handling you have already noticed to be less than what you desire them to be.

In this case I'd say the difference would be more cosmetic than performance based. 1/2" of rear height is not a significant difference when you're not slammed.

If you have access to a CAD program, I would recommend sitting down and building a model that shows the angles of your control arms with respect to the chassis and your wheels. Make sure to model in 3-D to make sure that camber gain(front) from the new ride height(and reduced travel) has been taken into account. There are some really good chassis engineering books out there that explain how so many variables can be designed to work together, and several of them speak in very plain terms, look around amazon for a good deal(no more than about $20). After creating your model, then it is time to test and tune, then re-evaluate after each iteration to understand why the single change created the result that it did. The most important part of this process is testing, because as the others have said, this is all very subjective, and iterative.
