I will say, be careful if you do install ROM Manager. DO NOT UPDATE YOUR RECOVERY USING ROM MANAGER. I have seen too many people brick their tablets. It may be fixed, but I would not do it.
Secondly - another thing to add, I just do a nandroid backup in TWRP. I have Titanium Backup Pro and this allows you to restore one app, or many apps from a TWRP backup. Much quicker than restoring from TiBu individual app backups. Also, TiBu Pro gets rid of the "Install" and "Done" popups that plague you when restoring apps using the free version. Not bad for 10 apps, but when you have 50-100 apps, that is 100-200 screen taps and makes the process take a lot longer if you forget to keep on top of it.
