Development on the Developer Edition Sneak Preview

My company will be installing the portal in about 3 months so Im tring to get a jump start on some development projects, however the more I read about and try to impliment configuration for the portal the more i'm questioning how much of it is installed in the Sneak Preview. I would like to play around with simple things like create Iviews from transactions, which i've read requires an ITS server, and more advanced things like develope dynpro pages and plug them into the portal, which i read requires a dynpro server. Does the Developer Edition come whith these things? Is there a good document out there that really walks through the configuration for them explaining details such as the installation location (url):(port) of the dynpro server or ITS server ... also does it matter if my R3 system has been upgraded to ECC5 yet or can i still use our 4.6 system as a valid jco destination?

thanks,

Roger
