We're about to switch from our old ISP to a new one. How do I assign static ISP-assigned IP CISCO ASA interface? Should I define it under NAT or Access Rules? Is it easier through console?

You assign the interface IP under interfaces.
(Configuration->Device Setup->Interfaces)
ASDM vs Console is a matter of preference. I stopped using the console after ASDM 6.x got launched, as you can do everything there.

Found it! Thanks! Could I still keep my old ISP ip just as a backup? I am assigning the new one for outside network. Oct 27, 2011 at 16:04

Yes, you could - but then you'll need to use another interface or create VLAN's (wich requires a managed L2 switch at a minimum)– pauskaOct 27, 2011 at 17:52
In the ASDM, it's under "Interfaces".
On the command line:
interface g0/X
ip address 192.0.2.45 255.255.255.0
And you'd probably also want a route for your new ISP, depending on exactly how you're coordinating the cut-over..
route outside 0.0.0.0 0.0.0.0 192.0.2.1 1
