Questions Regarding un official downloads

[RedDevil]

Glenn or Anyone,

When one goes to the downloads on your site is there any way of knowing which ones will overwrite previous ones?

is there any sort of order in which one can unzip them to ensure getting the most current version?

Are all of these downloads compatible with each other or are some overwriting the files and BMPS of others and making a mess of things?

I'd like to get the most with the least downloads, is there a General offerings package deal that compiles all the compatible downloads into 1 large zip and allows just a single download and unzip? :)

Thanks
