There used to be some good tutorials for SMB usage (easier entry and good use cases) on the nortel forums (then they became a sub in the Avaya forums.

Here's my real recommendation though.

If you want to move in the direction of managed switching in your home.office LAN get a better switch with some support in place. With this older and unsupported switch you're exposing it potentially to holes in the code that should have been patched in the interim.

you can get really nice used 24 port managed switches from Dell (power connect) Cisco and in the more SMB space from Netgear (as gfunkdave has posted above) for 50$. There are many options to get updates without going the route of the full S&M contracts or fees and they run pretty bulletproof. I will always change out Fans though (if you get POE models or some older models) to slightly lower throughput but significantly lower noise) so they can be put in a home office or room and not make any noticeable sound other than some slight white noise. If you don't need/want POE you can get finless that won't make any noise and still be managed.
