We have run out of wire runs. So to increase our network we will be putting a few hubs on different switch ports to increase the amount of pcs on the network. I have heard that it is important to make sure that any hub that is connected to a switch port that the port should be set to half duplex. Is this true? Also I have heard that port fast should be disabled. Are both of these suggestions valid? And are there any others that I should take head in?
Most hubs only function at 1/2 duplex so this might be the best setting for you. You might review the documentation for your hubs to ensure they are only 1/2 duplex capable. Go full if possible but don't mismatch settings.
Portfast being disabled is to help ensure there is never a bridging loop, since you are not supposed to connect any non-PC connection to a portfast enabled port. If you can ensure that your hubs will only have one connection to your switch you can leave it on... Best practices would disable this and allow STP to function on these hub connected ports.

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
