A word of advice: use it wisely. Just because you can make a form stand up and dance around the table, doesn't mean that you should. Take a look at some great resources about forms that are not focused on LC Designer. http://formsthatwork.com/. http://www.cooper.com/journal/. http://www.lukew.com/.

Then...
I would recommend JP Terry’s book “Creating dynamic forms in Adobe LiveCycle Designer”. It is an excellent starting point.
There are a lot of resources available online, which can help:
http://www.adobe.com/go/learn_lc_scriptingBasics
http://www.adobe.com/go/learn_lc_scriptingReference
http://www.adobe.com/go/learn_lc_formCalc
http://www.adobe.com/devnet/livecycle/articles/Adobe_XML_Form_Object_M odel_Reference.pdf
http://www.adobe.com/devnet/acrobat/pdfs/lc_migrating_acrobat_xmlform. pdf
And a very handy resource (and while it is for version 6 it is still very good because of the way it is laid out):http://partners.adobe.com/public/developer/en/tips/CalcScripts.pdf
The Help file in LC Designer can also help you with syntax and LC Designer itself comes with some great templates and examples.
Lastly, check out the Developer's Network on http://www.adobe.com/devnet/livecycle/
Also a book that doesn't deal with scripting at all but is very good on form layout is "Forms that Work" by Caroline Jarrett and Gerry Gaffney. The Adobe "PDF Forms Bible" is okay, but mainly focuses on AcroForms.
Windjack Solutions have a subscription based service for solutions and scripts at http://www.pdfscripting.com. It has a lot of AcroForm script that can be amended to suit LC Designer and a growing library of LC Designer solutions.
