The JBA and other fixed aftermarket UCAs are usually designed so that the cam bolts are in their factory "0" position when lifted, which makes it easy for alignment techs to do it a regular firestone. For this reason, you're alignment specs are actually pretty good for having no alignment capability. You'd probably be fine to run it like this for a little bit.
When the cam bolts seize into the bushings, it pretty much makes both the bolts and bushings trash. So long term, I'd recommend replacing the LCA and use new OEM alignment hardware. Optionally, you could rebuild the LCAs instead of buying new ones. Short term, you're probably fine as is.
If you want to see some nasty seized cam bolt pics and a taste of what replacing the bushings is like, heres a writeup of my LCA rebuild process:
