You also need the target platform - not everything on which JBoss Tools depends is already installed in Eclipse.
Here's the zip for offline use:
Once you've added the zip to Eclipse's list of Available Update Sites, select the JBoss Tools zip, and your install should proceed without the missing TM or RSE dependencies.
Let me know if that helps.
Thank you. I have already resorted to online install; however, this will be useful for the future.
