Get a LR 2 trial. Especially for beginners beta version can be tricky. If something goes bad there is not even a way to complain.
I use many beta products every day but I also have a very good backup workflow.
And--there are some issues with the beta. I can't open the print module. After installing, uninstalling, reinstalling, etc.---asking for help on LR beta forum--we haven't found anything. I haver a very straightforward setup--and have participated in LR betas since 1.0 without any problems.
I would dl the 2.6 30 day demo to begin with. I work with LR daily and really like it--thus I'm a bit frustrated that I can't try the print module, but anticipate the final version (and I agree--I bet there will be at least one more iteration of the beta and probably not a final version until later in the Spring--and of course, this is what beta's are for---to iron out the problems) will work fine. I wouldn't trust important files to a beta--and Adobe recommends this also.
Lots of tutes online--and a web based class would work fine too.
