Default [Q] [HELP] Installing Custom ROM & KERNEL

Hi I have an e987 (Personal Argentina version) LGOG and I recently unlock the bootloader with Freegee (v1.9.23) and TWRP (v2.6.3.3), and now I want to flash a custom rom with 4.4 KK, but, I really dont understand what to do. The steps for installing a rom are easy but,the questions are:

- How do I know what type of ROM (heehrc, gproj, etc) and what kernel I need for making that rom works?
- Can I use this rom with the Gee version and the stock kernel?
- What kernel is better for KK?
- Do I have to flash an specific baseband after I flash a rom?

There is a photo of my bootloader:

Thanks a lot.
