I rooted my Nexus but whenever a new Android OS downloads in System Updates it fails to update at all, possibly because the system is rooted or there is a new boot loader.

How do I upgrade the OS while my phone is rooted without wiping all my programs and settings?

I use Wug's Root Kit for rooting and backups.

download titanium backup
backup all user aps + data
wipe phone and install new rom
download titanium from the play store
restore all user aps + data

that will being back all your aps and data. and settings within those aps. Settings for the genral OS get reset unless you can back those up as well with a rom specific backup (which i dont think you are using)

Home screen locations and settings can be backed up in most custon launchers (is using one)

Titanium Backup also backs up Program Settings? I faintly remember doing this but I had to re-enter all my program logins and change the settings, like calendar entry colors and stuff.

It seemed to only restore the programs themselves.

System update is failing not because of root but what Wug did. Wug most likely replaced the stock recovery with Clockworkmod. That's automatic fail every time. Wug might have also installed Busybox which overwrote over stock files. Again, 100% guaranteed update failure. Your problem is you used Wug one click root without knowing what it did to your phone. That's the danger of using one-click anything. You don't know what it did so you can't fix it.

You need to restore the stock recovery. Then the stock OTA update will work. If it doesn't then it means Wug likely also installed Busybox and that modified your stock system files. If that's the case, you need to undo that as well. Good luck. Let this be a lesson and avoid one click solutions in the future.

I like the custom recovery (CWM) because of all the cool features like Nandroid Backups.

What does Busybox do?

The convenience of Wug's and not having to do any research on anything like searching for and then filtering through pages and pages of badly written root instructions that are all over the place far outweights the inconvenience of not being able to do a direct system upgrade.
