DSL does provide everything you ask for; e-mail is done with
Sylpheed, and as a simple word processor (with quite a lot under the hood) there's
Ted. You'll have to try and see if USB will work in order to be able to transfer your images.
DSL is great system; if you take the time to explore it and get to know the concepts, you'll find it very useful and adaptable, and the community is really helpful.
If you're a bit in doubt as to your ability to handle it, you might also want to take a look at
BeaFanatIX (
BFX 2006.2 is still beta but already makes for a very usable system); I've recently managed to install
BFX on a P233MMX with 64MB RAM - it doesn't exactly fly, but it works reasonably well, and if you're not a Linux die-hard, you might find it considerably more familiar than
DSL.
