Resource question

Hi all...
 
Where do you go to find the command lines, install tricks, etc you need to build a package and deploy software in SCCM?   I'd like to expand my resource list for data like this.  
 
I've got a client with a lot of apps they need to build packages for installation/removal etc.  I'm sure some people have already documented how to get the apps deployed, so I thought I would see where people here go to get advice like that.  I know much of this information is available at the developers sites, but I'm looking for other sites where that information might be documented.
 

Thanks!
