For any destination my habit is to check ALL sources of information
Yes. AIP (if the airfield is in there which many aren't), Pooleys (which is updated quarterly if you buy the loose-leaf version), airfield web site, and phone them first.
Pooleys has the advantage over the AIP that you can actually fit the whole book in the aircraft, thus if you have to land somewhere unplanned (as I did the other day) you've got the airfield info with you, rather than just having the charts printed out of the AIP for the planned destination and alternates.
