Something that surprised me not so long ago was that most digital cameras don't have many options you can control. Which means, even if it's a great little camera, you might not be able to get it to take pictures in the way you need. It probably isn't an issue if you've got a large budget for a higher end SLR (digital or otherwise) but for the non-SLR cameras, it's an issue. I got a Nikon Coolpix, for example, which works amazing for %99.99 of anything I'll ever use it for (although I probably could have saved some coin on a Canon A series...or a couple other manufacturers...but I digress). It's got more "settings" than I can count, but I can't tweak the set-up to get clear pictures of rain drops or optimize things for any situation. So, if it is something you never knew, like me, keep that in mind when shopping around for a camera. Also, I got a Joby tripod (one of those flexible ones) and it's got no stabilization what so ever. No matter how tight you wrap the legs around something, it tends to move the camera when the button is pushed. So, with a delay it might work well for some folk, but I expected more.
I've long since lost all the websites I had bookmarked for photography and cameras, but there are tons of them out there. It is a fairly popular activity, after all. So you can try doing a web search for instructions and tips and settings, etc. Include the type or subject matter you'd like to photograph for a more specific set of results. You're guaranteed to find answers quickly, just make sure to cross reference your results, like with anything online, you never know how reliable anything is.
