Wireless transfers are slow. There is no other way to say it. It doesn’t really matter how you have everything configured (within limits) because the speed isn’t going to be as fast as a wired connection. As long as you don’t have your MBP and TC on the outer edges of your wireless network you should have maximum speed (as pitiful as it is).

As for your second to last question, no there is no way to have it do a “sideways” transfer. Everything has to go through your wireless router. As far as your computer and TC are concerned they aren’t sitting next to each other, they could be at any point in the radius of the wireless network.

And your last question: yes, you should be able to configure the TC to extend the signal from the other wireless router. I forget exactly where the settings are inside of AirPort Utility but they are there.

No problem. Always trying to help out people who make the switch. Hope you enjoy your new Mac!

You almost have it right. What you need to do is enable Fast User Switching.

To do this open System Preference and go to Accounts. Click the lock and then go to Login Options. At the bottom there is an checkbox next to “Enable fast user switching” check it.
Now go back to the main view in System Preferences and go to Security and enable “Require Password to wake from sleep or screen saver”.
Now, just activate the screen saver and then move the mouse. There will now be a button that says “switch User” clicking this will bring you back to the login screen.
Hope that helps.
