New to Cisco, ASA5505 Help

Question

Afternoon guys,
I have decided I want to learn Cisco so made the decision to pick up a used ASA 5505 from ebay and use it as my main firewall/router. I have it installed and working but have a few questions about configuration, as some of what i have done seems like a very inefficient way of setting things up.
My Basic config is this
O2 ADSL Modem in bridge only mode  192.168.1.254 > ASA 5505 Public Static IP >ASA Inside 192.168.1.1 > Rest of internal LAN.
I have spotted this blog post that details how to get to the modems WebUI through a Cisco router, But i am not sure how I would implement it in my network setup so would like advice on this.
http://en.tiagomarques.info/2011/05/access-your-modem-webui-behind-a-cisco-router-bridged-configuration/
O2 Modem IP: 192.168.1.254 ASA inside IP: 192.168.1.1Apple Airport: 192.168.1.2 (Wireless Bridge)LAN : 192.168.1.0/24 (VLAN 1)
The other thing I would like to ask is about PAT, I have configured it to allow Ports 3074TCP/UDP and 88TCP inbound to my Xbox to allow Xbox live to work. But I would like to know if there is a better way to do this using object groups.
This is currenlty how I set it up,
object network xbox_udp_3074host 192.168.1.5nat (inside,outside) static interface service udp 3074 3074exitaccess-list acl_outside extended permit udp any object xbox_udp_3074 eq 3074object network xbox_tcp_3074host 192.168.1.5nat (inside,outside) static interface service tcp 3074 3074exitaccess-list acl_outside extended permit udp any object xbox_tcp_3074 eq 3074object network xbox_udp_88host 192.168.1.5nat (inside,outside) static interface service udp 88 88exitaccess-list acl_outside extended permit udp any object xbox_udp_88 eq 88
What I would like to know is there a better more efficient way of setting this up as I have 3 network objects with 3 NAT statements and 1 ACL.
Finally I have attempted to configure a Client VPN on the ASA and it works and connects but the problem is it only appears to let web traffic through. If i connect using the VPN built into my iPhone and try a ping using using Ping Lite app i dont get any responce's. but if you open safari and put in 192.168.1.4 I get the WebUI of my NAS device if i try to RDP to my home server the connection times out. If i drop the VPN and connect to Wifi i can ping and RDP from my phone ok so it must be a config problem.
Below is my full config I have masked the password and cryptochecksum

Hi,
Adding the following configurations should allow ICMP through the ASA (for the echo-reply to come through also without using ACL)
policy-map global_policy class inspection_default
    inspect icmp
Unless you had already added this.
You might also find the following documents/video helpfull. It shows off some of the common NAT configurations. This was mostly to help the people that were moving from the old to the new format. But it should be helpfull to you also. I know I sometimes double check there.

Video: https://supportforums.cisco.com/docs/DOC-12324 (also has a link to the above document)
Regarding the NAT configurations for modem management, I cant guarantee this will work but the first configuration that came to mind is the following (kind resembles the NONAT configuration)
Though I'm not really sure if this would work as the LAN network and the outside management IP is from the same network. But you can always try.
object network LAN
  subnet 192.168.1.0 255.255.255.0
object network MODEM-MANAGEMENT
host 192.168.1.254
nat (inside,outside) source static LAN LAN destination static MODEM-MANAGEMENT MODEM-MANAGEMET
