    Retention levels should meet recovery needs.
    This is a business decision, not something that we can tell you.

    Yes, you should keep Full backup on disk at least till after next full backup.

    When using client-side dedupe with accellerator, you can do full backups all the time. Although the net result will in effect be incremental backups, the image catalog will be for fulls. So, this means increased catalog on the master.

Weekly full backup retention is up to your business requirement, but if that's up to you to advise your team, think of the storage capacity and how far you want the ability to get your (old) data back to?

Usually in the business they also have monthly / quarterly / yearly backup to keep for longer term, and a weekly usually has retention of at least 1 month or longer, depend if you want to have the above defined.

I would keep Full+incremental. Accelerator feature can be beneficial but do take note it does not replace your incremental. Having Full with accelerator turned out can appear the same, but would increase your catalog size!
