Roaming aggressiveness is often in need of decrease in dense WiFi environments of current offices, clients are bunny-hopping between APs on default values. Thats probably all you can change in client setting, all other parameters depends more on AP settings and useless without proper support from all devices in WLAN.
A couple of things that have been mentioned are disabling the WiFi when users are connected via Ethernet and also ensuring that the clients prefer 5Ghz.
Roaming Aggressiveness has also been mentioned but our network team had recommended increasing ie Making it more aggressive rather than decreasing.
It does seem that everything that we try doesn't seem to make a difference so my thoughts are that we have some underlying issue with our Wireless Configuration.

It`s easy to check for you, tools like Wifi Analyzer and inSSIDer (for Android Phone) will show you many parameters of WiFi environment, using simple color scheme to indicate quality of WiFi in different aspects, including distances and signal strength of nearest APs. Again, main side is on WiFi APs itself, if this is an rich solution from Cisco or Ubiquiti - admins have (or can have by some software upgrade) tools for complete network tests and analysis, and a lot of ways to change APs settings accordingly. If that is cheap controllerless commodity pods - unlikely anything can be done on client side.
