I'm in the early stages of planning a western balkans (Slovenia, Croatia, Bosnia Herzegovina and part of northern italy) vacation. It seems like many people around here have done some travelling in this area and I'm looking for some input.

What locations are a must see? What locations should be avoided? What reference material is the most useful (I have Europe on a shoestring right now by Lonely Planet)? Most importantly I'm trying to find a croatian/slovenian/serbian etc. language guide. Are there any recommendations regarding that?

The locations that I definately want to see right now are Lake Bled in Slovenia, Dubrovnik, Split and some of the islands in the adriatic. Looking to do about a month long trip.

Thanks in advance.
