Deprecated global & nat commands on ASA

I am putting a new Cisco ASA 5510 in place to upgrade a site from small Cisco ASA-5505 firewall.  I am extremely familiar with the older versions of Cisco's IOS software, but ran into a deprecated command that I need translated.

Here is the old commands under teh ASA-5505:

global (outside) 1 interface
nat (inside) 0 access-list VPN
nat (inside) 1 0.0.0.0 0.0.0.0

But these commands do NOT work, and are deprecated under the IOS ver 8.3 on my new ASA-5510.

Can anyone tell me what the new commands are for this?  It mentions using the "nat" command, but I do not know the syntax.  (Also, are that any EASY TO FOLLOW, documents on what commands have been deprecated from one IOS version to the other, and what those new commands are that provide the same functions?)

Thank you for all help in advance,
Jeff
