Hi Fernando! Personally, I think the Vue manuals have been excellent. I haven't seen the v.4 manual yet, but I've got v.2 and v.3. The only thing they lacked was an alphabetical index, but I think an index has been included for v.4. The manuals typically have an introduction to each facet of the program, plus tutorials for many operations, and also additional tips and details. What I like best is that it's written in an "easy to read" style. For more tutorials, check the Tutorials link in the sidebar here at Renderosity. You'll find several tutorials for Vue around the web. (I don't think there are any v.4 tutes as yet.) Each version of Vue comes with several SolidGrowth plants/trees, and there is additional vegetation available from the E-on Software website. The SolidGrowth veggies are low-polygon items that are each unique, so your trees don't end up looking identical, even of the same species. But you can use regular 3D model vegetation also, and I think that would be the CDs you heard about. Hadn't meant to write a book, sheesh! Hope this answers something! :)
