Do more cables = better Bandwidth ?

All,
I am no physics major, but If I have 1 cable comming from 3 daisy-chained 24 switchs from another part of the building, to the main switch, could I improve any aspect by running 1 or 2 more cables to the main switch?

The 100 baseT network sometimes is dog slow. All the switches are on the third floor and the servers and the main Catalyst is behind me on the second floor.

I can easily do this if it will benefit.

It is highly unlikely that your 100 megabit cable is the bottleneck unless the cable is either damaged or being interfered with.  If you are experiencing a slowdown that is percieved to be a result of the cable, I would highly suggest using a set of wire testers to ensure the cables integrity.  Additionally, as you know the maximum length that CAT 5 ethernet can be run is 328ft (100 meters).  If your length between the switches and the main switch is greater than that, then you will see a performance issue.  Do you see any dropped packets when you do a long ping test (ping -t)?  Is the latency very high?  Additionally, other things can distort the signal such as certain types of lighting.  

All in all, it is unlikely that an additional cable or cables will help, but instead i think you need to troubleshoot the existing bottleneck.  On a 100mbps network you should not see such horrible speeds.

You would also want to run a packet sniffer at your machine, and various other network connections to look for irregular traffic.

No, the latency is normal, 128TTL. No dropped packets. The run is about 115  ft max.
This building is was at one time a office with multiple suites across 3 floors and now we have the whole thing. The phones are wacky too, having 5 different vendors doing the separate suites and then having someone combine them and not document it.
  I'll have to start from square one. Thanks.

Yeah sounds like the usual wiring mess.  I'd run a couple network utilities to see what might be causing the issues.  Perhaps running a new wire may fix it and be the easiest solution.  Good luck sorting it all out.
