which subscription ?

Hello

I am new to Netweaver Administration and would like to enrich my knowledge in Adminsitration area more by having authentic information.

So i am looking for some kind of subscription with which i can get information on how individual SAP systems in landscape can be configured to connect to .Net box, configuring Portal system for connecting to BI, XI, configuring SLD, configure various services on Java based SAP system....e.tc ...more on Adminsitration side only....

Could some one pl suggest whether SAP TechEd eclasses have such Administrator usefull information or not, so that i can make some decision ?

Thanks
