Hacking Need some help with Gateway

[trsoares]

I asked this in the Noob Paradise Topic, but seems nobody was able see it because the great number of posts.

I downgraded the 3ds yesterday .

Using Gateway, i already did the backup of the sysNAND, installed and updated the emuNAND and tested some .cia games with FBI.
Seems all is going fine . (Still need to unlink the nands , forgot to do that)

For now , i just want to know if :

1 - Can i boot my 3ds direct (just after power on) in Gateway Menu? (Or in emuNAND)
2 - Can i install FBI (the .cia archive) and use it in the 3ds menu like it was a game ?
3 - And do the same with HBL (with Homehax or something) ?
4 - There is any other homebrew that i may find usefull with Gateway?

Thanks!
