As far as I know market is not working with touch nooter 1.1 so far
If you want to install non market apps after root the first thing you should do is open nookcolor tools from the apps see if allow non market apps is ticked or not even if it is enabled I would recommend disabling it and then enabling it. Then copy any app you want to the nook from your computer use root explorer to install it. I would recommend installing and using dropbox as it allows to transfer files easily between nook and your computer without wires.
If you don't have a dropbox account use my referral link at it will extra 250Mb free to both of us
