Default [Q]few questions before installing cm on d802

Hey every one,

I have the lg g2 d802 on the moment i'm using
stock ROM 4.2.2(D80210b-ISR-XX)
Base band M8974A-AAAANAZM-1.0.190036
Kernel 3.4.0
Build Number JDQ39B

I rooted my G2 with cwm

i understood their is an issue with ROM flash
that forcing the G2 into recovery boot loop

so i wanna ask what to do ?
i wanna avoid the boot loop

the other thing i wanna ask it's if their is an option to use cm installer for this version? if yes, it's safer?

the last question i wanna ask it's if someone could tell me witch gapps i should use?
on cm site their is an torrent link for gapps for cm11
but when i'm looking for it on the last version it's for cm10.2.x

thanks in advance
and i'm sorry about my English
