Good question. I am still on LPS. I like the responsiveness of the touch screen compared to some others I tried. I guess LP8 would be fine. I am also using Siyah kernel which seemingly gave me better wi-fi (but that could be just placebo effect). I will try NEAK kernel later when the new version comes out. The current one has issues with freezing when charging.
I don't know where you get your FW from. I get it from Intratech's thread on XDA. And I get my CF-root kernels from Chainfire's thread. As a rule when I flash a new FW, I do a nand backup first and the first kernel I flash is CF-Root. If that all works well and I find no issues, I try out some other kernels that suits performance or battery life better.
The Wanamlite ROM is LP9 and they use the CF-root LP8 kernel to prevent the critical error. Just read the last couple of pages of their thread/forum and you will know if there are issues with the combination. I tried Wanamlite once and was not really impressed so I reverted back to stock LPS.
