Go to the gate at 8AM and enter the actual city with your Day Pass.
Go talk to Val again, and if you've given her the pliers and wrench last time, now she'll give you the super toolkit that the ghoul in Gecko wanted. She can also modify weapons, but don't do it now.
Talk to the officer in the Correction Center, if you've scouted around
Gecko, for your reward. Ask for more work, and you'll get an
assignment to scout the road to NCR. You'll do that much later,
anyway. Also talk to him about the raiders.
Go to the Council. Don't talk to the First Citizen, or she'll sic the
guards on you for trying to fix the ghouls' reactor instead of
slaughtering them. Talk to McClure, the councilman in the right-most
room, and tell him how you can fix the plant in Gecko. He'll say it's
an acceptable solution, and authorize you to pick the Hy-Mag from
Amenities. Tell him you're affraid Lynette will not make you a
citizen if you repair the reactor. He'll tell you that he'll make you
a citizen himself. Also give him the economic data disc from the
greedy ghoul in Gecko. More xp for you.
Go back to amenities, and pick the hy-mag. Leave for Gecko...
