Networking & wireless forum: Home Network Assistance Needed!

I have setup my wireless network, and things are working mostly well, but I feel as though I am about 80-90% there (feel free to correct me if I am more optimistic than I thought!)

I have Road Runner Lightning internet through Brighthouse Networks. The advertised specs are: 40mbps download / 5mbps upload. I have completed SpeedTest.net testing and it ranges from 25-35mbps down/4-5mbps up, depending on time of day etc. Anyways, Brighthouse makes you use their router/modem combo which is made by Ubee.
Here is my setup:

Spare Room/Office: Main Gigabit Router/Ubee: 192.168.0.1, DHCP on, set to Mixed Wireless mode (N/G). Ports 1 and 2 are linked to my other two routers. Port 3 is connected to a Western Digital MyWorld Network Attached harddrive. Port 4 is connected to an external GreenNet 8 port gigabit switch for expandability.

Family Room: Linksys E1000 N Router w/ DD-WRT installed (192.168.0.253) in Family Room which connects HD Tivo and Samsung SmartTV. Router is set to "G/N mixed" mode and router is setup as an access point. DHCP is disabled on the router, Port 1 on the router is connected with Ethernet to Port 1 on the main Ubee router.

Living Room: Linksys WRT65GS w/ DD-WRT installed (192.168.0.252) in Living Room which connects to Series II Tivo, Samsung SmartTV, Samsung Blu-Ray player, and Samsung Streaming Media Player. Router is set to "G only" mode and router is setup as an access point. DHCP is disabled on the router, Port 1 on the router is connected with Ethernet to Port 2 on the main Ubee router.

Master Bedroom: Trendnet Gigabit 5 port switch connected to Samsung SmartTV, Apple TV, and Series II Tivo.

\Wireless Clients: Wife's laptop w/ generic N usb adapter; Ipad2, Ipod touch, Iphone, Nintendo Wii

All routers are set up with the same SSID and login information. The main router is set to
Channel 1 and the other two routers are Channel 6 and 11, respectively. Transmit power was increased to 100mw on the DD-WRT routers. The two Linksys Routers were assigned as "static leases" to the main Ubee router using the MAC address and IP address of the routers.

My main PC which serves media content throughout the house is not currently wired, but I am working on that. It will eventually be hard-wired via Ethernet to the main Ubee router.

What else do I need to do? Would you change anything in the setup (short of replacing the routers?). What must-needed settings should I use on any of the routers? Please critique my setup! Thanks in advance!
