Answer 1

A device can be connected to only one network at a time.
I will tell you what works for me.
Connect your TC to your modem. All you need to do is set up a dedicated n network on 5ghz freq (i used wpa2 wireless security) with with your TC and use that with all of your other n capable stuff like ATV, macbook air etc. Then connect your old AEBS using an ethernet cable to the ethernet AEBS connection to the TC ethernet. Then using Airport Utility find your AEBS, and set up a b/g network 2.4ghz freq (i used wep 128bit). While setting up the AEBS, click on the internet tab on the top and then go the bottom, where you will see connection sharing and select off (bridge mode). This will allow your AEBS to use the TC as a bridge to your cable modem. Now you have two wireless networks using one modem using essentially 2 base stations, TC and AEBS. My old AXs, old b/g imacs and iphone join the b/g network, and I can stream music from my n capable computer and old b/g imacs to my ATV and AX hooked to different stereos around my home. And log in to different music libraries and control the music from my iphone. My computer are all networked wirelessly. The higher encryption you use on the b/g network the slower it will be. Do not combine b/g/n network as it will be slow, and more so using any wireless security. Keep in mind you can also use an old AX instead of and old AEBS for the b/g network as well in bridge mode. Give different names for each network. Any neighbor on the same frequency using the same channel will interfere and slow your network done. There are cool widgets you can download that tell you what channels your neighbors are using and can select a different channel from them. It's complicated and takes patience, good luck.
