Firstly, i would make sure the final touches are complete.
I would then explain to Axl and the band the possible release dates available, and agree with them on a marketing strategy and time-frame including singles and video shoots.
Once agreement has been reached, announce publicly a release date for album, and drop the single on the radio.
Get the band (or just a couple of members) on interviews..Letterman, Jonathan Ross, MTV etc.
Then just make sure promo work continues up until and when the record is released, and hope all goes well. I would probably have a signing session after the 1st week of sales.
Then I would speak to Axl about touring- where would he want to go and when would he be ready to start?
