From the looks of it the vbk is the initial file and the vib files are the delta changed files? If I have an archived 1-1-2015 vbk (archived on an external drive in a safe in a remote place) and just the 2-1-2015 vib file I can restore all the 2-1-15 files? I don't need the intermediate 1-2, 1-3, 1-4-2015 files correct? Are these correct assumptions.

Somehow I've got vib files that are larger than my vbk files. And my initial 1-1-2015 vbk (non archived, connected to the server) file was replaced with a more recent date, I also have a vib file that is slightly larger than the large vbk file. This will pose a problem in the future as space becomes a concern.
 
You are way off.

Veeam creates a full backup and then every back after that is incremental off of the previous backup. Every once in a while, based on your settings, Veeam creates another full backup and you get a new incremental chain. So, if you only have the full backup file and 1 of the latter incremental files (not contiguous with the full) of that specific chain, you can only recover the full backup.

Incremental backups can be larger than the full backup. It means that you added new files and probably changed a bunch of files since the last backup.
 
You can also do reverse incremental and then you'll have a full backup as the latest backup with the differentials going back to where you have your retention policies set. It is very disk intensive though, so if you're using a dedup appliance you probably don't want to do reverse incrementals. Best to check with your vendor.
