TelNet & SSH

What is the difference between these two? and what is the advantage of using them?

does anyone here use either of these, and if so what for?

SSH is a secure version of telnet (i think). They are both basically ways of connecting to a remote server to administrate it through the command line/terminal. It is like remote desktop, but in commmand prompt.

I use SSH to connect to a Linux computer I have for testing stuff, and to connect to my wbe host where i can install/update php and see information about the server

ssh creates an encrypted tunnel from point a to point b, and in some cases if set up right from point a to point b to point c. In a sense you are "telnetting" when using ssh, the main difference is ssh creates an ecrypted tunnel between connections so nothing is sent across the network/internet in plain text.

so when connecting via telnet, no encryption is used? Does this mean this information via telnet could be intercepted with a packet sniffer?

correct, also free version of VNC is not encrypted which is why i use putty, or another ssh client to create an encrypted tunnel first, then use VNC to do remote connections.
