<p>Is there guide out there that will help me, A .Net developer whose been using Visual studio for some time, get to grips with Eclipse?</p>

<p>Even just a quick guide to eclipse.</p>

<p>Has anyone else made the transition, and if so how did you cope. Any Tips?</p>

Not sure if it will help you, but Eric Sink ran a nice four part series some time ago on his move from VS to Eclipse:
From C# to Java - Part 1
From C# to Java - Part 2
From C# to Java - Part 3
From C# to Java - Part 4
