I think it limits the size of application you can run, although a big 
application would live mostly in swap and run slowly, and you're unlikely to do 
that. I can't think of any big benefit, either, if saving a few bytes is an 
issue you should build a custom kernel and cut out anything you don't need.

No, I have both kernels on several machines and have booted them, at one point 
the PAE would blank my display on boot and the non-PAE worked (but only used 3 
of 8 GB RAM). That went away a while ago, but either will work.

If you think it will make a difference try it, it will boot and run.
