alcatel android adb interface,Android Eclipse: Ruined my emulator plus can't detect new Alcatel phon...

In the last 36 hours, I've managed to screw my eclipse settings .. from being able to run my app, to now not even launch the emulator properly.

I think it started when I modified the AVD's SD card size and added a camera. Since then I've deleted the AVDs and recreated them. But eclipse now takes 20-30 mins to launch the emulator, and fails while trying to install my apk. When the emulator finally runs, I can't find my app so its not as if its installing and only failing to launch.

Also I bought a new Alcatel Onetouch 918n phone. After some painful steps, I now see "Alcatel Android ADB interface" in Device manager. But I just can't seem to make this phone visible to Eclipse/ddms/adb.

I don't have many logs to paste here- not sure what I should include. HELP!!!!
