Yes, you can do this.
You can backup all your filesystems using ufsdump to a remote disk over NFS. (You should use "fssnap" before ufsdump on each filesystem to snapshot.)
If your system crashes and won't boot then you can boot from CDROM and mount your hard disk root filesystem on /a. You can, if you need, then "newfs" your root slice ready to take a clean restore.
Use the ifconfig utility to plumb and configure a network interface so that you can ping the remote box where your root ufsdump is sitting.
Then mount the remote filesystem containing your ufsdump on /mnt.
Change directory to /a and ufsrestore your dump file of the root.
Job done!!
Of course, you may need to restore other filesystems in the same way (eg /var) before your system will boot depending on how you installed everything in the first place.
As far as patching is concerned you could store patchsets on your central box but you should ftp them to each server for patching because it is strongly recommended that patching is done in single user.
Just post if you need any of the above expanded.

Another route would be to use flarcreate to create a flash on your cental server.
To recover boot from CDROM and do a "flash" install.

quotaoff
QUOTAON(8) BSD System Manager's Manual QUOTAON(8)
NAME
quotaon, quotaoff -- turn filesystem quotas on and off
SYNOPSIS
quotaon [-g] [-u] [-v] filesystem ...
quotaon [-g] [-u] [-v] -a
quotaoff [-g] [-u] [-v] filesystem ...
quotaoff [-g] [-u] [-v] -a
DESCRIPTION
Quotaon announces to the system that disk quotas should be enabled on one or more filesystems. Quotaoff announces to the system that the
specified filesystems should have disk quotas turned off. The filesystem must be mounted and it must have the appropriate mount option file
located at its root, the .quota.ops.user file for user quota configuration, and the .quota.ops.group file for group quota configuration.
Quotaon also expects each filesystem to have the appropriate quota data files located at its root, the .quota.user file for user data, and
the .quota.group file for group data. These filenames and their root location cannot be overridden. By default, quotaon will attempt to
enable both user and group quotas. By default, quotaoff will disable both user and group quotas.
Available options:
-a If the -a flag is supplied in place of any filesystem names, quotaon/quotaoff will enable/disable any filesystems with an existing
mount option file at its root. The mount option file specifies the types of quotas that are to be configured.
-g Only group quotas will be enabled/disabled. The mount option file, .quota.ops.group, must exist at the root of the filesystem.
-u Only user quotas will be enabled/disabled. The mount option file, .quota.ops.user, must exist at the root of the filesystem.
-v Causes quotaon and quotaoff to print a message for each filesystem where quotas are turned on or off.
Specifying both -g and -u is equivalent to the default.
Quotas for both users and groups will automatically be turned on at filesystem mount if the appropriate mount option file and binary data
file is in place at its root.
FILES
Each of the following quota files is located at the root of the mounted filesystem. The mount option files are empty files whose existence
indicates that quotas are to be enabled for that filesystem.
.quota.user data file containing user quotas
.quota.group data file containing group quotas
.quota.ops.user mount option file used to enable user quotas
.quota.ops.group mount option file used to enable group quotas

The quotaon command appeared in 4.2BSD.
