[HELP] Can't get Slim GAAPS to work topic

Hey guys, so i'm trying to install the following items:

-SlimLp F2FS (Android L)
-M-Kernel_a73.zip
and
-Slim_full_gapps.BETA.5.0.x.build.0.x-20150213-482

I use NRT to get into TWRP and from there I follow the following steps (my system is already in F2FS mode which i reformatted from the existing Ex?? one)

Clean Flash:
Wipe syste, data, cache, dalvik cache
Flash the rom
Flash Slim gapps or L Gapps (IDK WHAT THE DIFFERENCE BETWEEN GAAPS AND L GAAPS IS and they take me ultimately to the same link so wtf)
Reboot


The main issue is, after the tablet reboots and opens up I don't see the play store, i don't see ANY google items and I can't install anything. It seems to me that the GAAPS zip isn't being installed properly. I've already installed the main ROM, then GAAPS, then the M kernel and nothing seems to work. I don't see any playstore icons even in the app drawer. Can someone please explain to me what i'm doing wrong? Thanks!
