After opening the site, please select the Source Release Version which is 4.6 b Then Select the Target Release Version which is "mySAP ERP 2005" or ECC 6.0

Hi Rohith

well ECC is built up on Netweaver platform making it very simple to integrate with any Legacy system, While R/3 is based on WAS 6.20, ....6.40 whcih does not have complete integrated ERP , here you need to install additional packages such as CRM , etc if you want to use them ... but with ECC it comes as central component

For second Query check this

Hope this helps
