When I do a crypto ipsec transform-set ?
I see:

ah-md5-hmac
ah-sha-hmac
comp-lzs
esp-des
esp-md5-hmac
esp-null
esp-sha-hmac

I always choose esp-des.
When's the proper time to choose ESP and when's the proper time to choose AH?

You can use AH alone when you are just looking for authentication and anti-replay services without encryption.  If you want encryption you need to use ESP.  ESP also provides authentication.  Typically you are going to use ESP for your VPN tunnel.
