Move To Another Host With .Tar.Gz Backup File

I'm thinking about moving an account with one main domain and a bunch of addons from one cpanel host to another, using a whole site backup .tar.gz file. SSH does not appear to be an option at this point.

I just extracted the tar.gz to a local pc to get a look at what's in it. It has these 12 folders: bandwidth, cp, cron, dnszones, logs, meta, mysql, resellerconfig, userdata, va, vad, vf. Below these folders are also 14 unfoldered files, ranging from "addons" to "version."

So, will this work?

1. Does this mean the domains and all the addons will be set up with their original user names, passwords, and email accounts with all the same passwords, if I move everything to the right location? Will all the email accounts I've set up in my email client software work just as they do now with the current host?

2. How can I know where all these uploaded folders and files have to be moved once they're there?

3. Can I just upload the extracted contents to one location, or do I have to upload the unextracted tar.gz to a server, extract there, then move the contents wherever they need to be moved (but I don't know where things need to be moved now)?
