The GUI for managing plugins in Eclipse got a bit of an overhaul in version 3.4.0. This GUI is accessed via the "Software Updates..." option in the Help menu.
The option to remove the selected Mylyn plugin is greyed out. In fact, this is true of virtually every installed plugin. I know that the Mylyn plugins are optional, so why amn't I provided with an option to remove them?
In the "Installed software" tab click on the software that you wish to uninstall, then click the "Uninstall..." button below. If you installed the plug-in by dropping into the dropins folder, then just delete it from the dropins folder and restart Eclipse. See the answer of @Cogentleman for more recent versions of Eclipse.

(On Macintosh it is Eclipse > About Eclipse > Installation Details .) In older versions, you might need to Run Help > Software Updates > Manage Configuration... , select the feature of interest, and disable it with the task shown in the right window. 'Uninstalling' a feature, using the steps above, disable the feature or plug-in.
In eclipse Helios (version 3.6), to uninstall a plugin: Go to Help->Install New Software... Click on "What is already installed?" link at the bottom right side of the dialog Click on the "Uninstall..." button at the bottom Click 'Restart Now' when prompted to do so. Eclipse restarts. Choose the workspace.
The following text is quoted from the Eclipse help docs:
The Uninstall wizard allows you to review and uninstall items in your configuration. This wizard is shown when you select items and press Uninstall... from the Installed Software page. To uninstall software from your system:
Click Help > About and then click Installation Details... to open a dialog showing pages that provide more detail about your installation.
Click the Installed Software tab to see a list of the software items that you have installed into your system.
Select the items that you wish to uninstall.
Click Uninstall...
The Uninstall Details page will show you a list of the items that will be uninstalled. Expanding each item will show what additional items (if any) will be uninstalled as a result of your choice.
If you change your mind about which items should be uninstalled, you may click Back to see a checkmark list of the items you selected before. You may check and uncheck different items in the list, and click Next when you are ready to continue.
Once all of the software is uninstalled successfully, you will be prompted to restart for the Workbench. Click Yes when asked to exit and restart the Workbench for the changes to take effect.
And just to update it for Helios - Eclipse 3.6
