In order to use your Eclipse with Visual Studio keyboard shortcuts, you need to go to Window->Preferences->General->Keys and pick "Microsoft Visual Studio" from the scheme dropdownlist. That's it in short, happy coding...

While using VS.NET, I generally find and replace all through the project(current project, entire solution, etc.) via Ctrl+Shift+H. However, in Eclipse it seems there is not any direct alternative at first. But what you need to do is pressing Ctrl+Shift+F, moving to "File Search" tab, picking project scope(enclosing project, workspace, etc.) and clicking Replace button in order to start replace operation in a wider scope. I personally like the VS.NET's way of doing this operation.
