Can two ports on a 2950 be configured to be uplinks to a another 2950 to provide redundancy and performance gains, or would it be preferable to install gbic modules and run fiber? Distance is about 200'.

Yes.

However, by default, the Spanning Tree protocol will block any redundant paths leaving only one to forward frames.

You can use EtherChannel to utilize all links between switches.

Is EtherChannel a seperate product or is it already incorporated into the switch?

Yer welcome.

To enable it,

int range f0/1 - x  ;(you can group 2, 4 or 8 ports although I can't remember if the 2950's support 8)
channel-group 1 mode desirable

Just make sure that all port are configured the same (VLAN, trunking, speed, duplex... everything).

In the world of WAN, QoS is a pretty important topic for most, if not all, networks. Some WAN technologies have QoS mechanisms built in, but others, such as some L2 WAN's, don't have QoS control in the provider cloud.
Getting hacked is no longer a matter or "if you get hacked" — the 2016 cyber threat landscape is now titled "when you get hacked." When it happens — will you be proactive, or reactive?
