Thanks bnt - I did the same, but trying to add the ADT Plugin in Eclipse/developer tools it kept telling me
" Software currently installed: Eclipse IDE for Java EE Developers 1.3.1.20100916-1202 (epp.package.jee 1.3.1.20100916-1202)
Only one of the following can be installed at once:
Eclipse UI 3.6.1.M20100826-1330 (org.eclipse.ui 3.6.1.M20100826-1330)
Eclipse UI 3.6.2.M20110203-1100 (org.eclipse.ui 3.6.2.M20110203-1100)" etc etc which was, unfortunately, meaningless to me and I cannot find any forum to ask.
