The most important thing to understand about CCX is that the scripts are Java. Sure there is a GUI that abstracts a lot of this from you; however, it is still an IDE and you are writing Java code. The prebuilt Java beans [steps] can only take you so far. I find myself adding raw Java code into my scripts more often than not to make them do what I want. If you are not a programmer already, you will struggle to flourish with CCX scripting. You would do yourself a huge favor by taking a few semesters of programming classes at your local community college first.

As for study materials: There are no published books at present that walk you through CCX soup-to-nuts. Your only options are the Cisco Learning courses UCCXD and UCCXA or the product documentation. The documentation is great for those who understand the product but it can be a little bit of challange to get your head around the product based solely on the documentation.

My suggestion is to start with the getting started guide, release notes and SRND document. The UCCXD and UCCXA classes are really great, especially if you have a good instructor who knows the product. If you can get your employer to pay for them, they are the way to go.

Lastly, there are a few scripts available publically that you can use as a reference in the Cisco Contact Center Express Script Repository.
