Is there any alternative keyboard for Android HTC Desire 2.1 that supports English/Czech dictionary and easy way to switch between them?

Sometimes I type in German and sometimes in English. I seem to be only able to switch on autocompletion for one language and have to add the words of the other language one by one to the dictionary. Is there a better way for those people who are multilingual?

Is Hebrew support built into Android? If so, is it in all versions?

I have some MP3 files that have Cyrillic in the mp3 data, as well as being named Сyrillic (the file names themselves as in "музыка.mp3". Is there some additional language package that can install to have my music player and file system render the Cyrillic data correctly? I realize these are two separate features. I'm happy to get answers for both. TIA
