In Window > Preferences > TextMate > Theme there's the ability to add and remove TextMate themes.

Does this mean that Eclipse supports TextMate themes, and if it does, how do I apply one of the themes?

Here's a screenshot of the menu:

Yes, you can add here CSS files used for syntax coloring for languages and formats that are based on a TextMate grammar: see preferences Language Servers for the supported languages/formats (there can be language/format support only for syntax coloring via TextMate grammar, but - as far as I know - all built-in languages/formats support code completion, etc. via language servers). See the built-in themes which can be used to create your own theme.

A file with syntax coloring via a TextMate grammar has to be opened in the Generic Text Editor: choose a theme via right-click and Switch to Theme....

Please note, a TextMate grammar for syntax coloring of a specific file format can currently be added, as far as I know, only via an Eclipse plugin.
