SpringBoard is basically the name of the "desktop" of your iPhone or iPod Touch, just like "Explorer" is the name of the one for Windows-based machines, and just like how "Finder" is the name of the one for Mac OS X-based machines.
WinterBoard is just the name of the app that let's you change the way SpringBoard acts and looks.
To open app that you have downloaded (through the App Store or through Cydia/Installer), just find the app in SpringBoard and tap it and it should open*
* How To Use Winterboard *
Winterboard is way to customize your iDevice by putting themes on there*
Some themes are complete, some are for Springboard only, some for Lockscreen. Most themes have screenshots that cam be previewed before you download it.
After installing a theme, go to Winterboard (if you can't find the icon, it is probably being hidden in Settings.app). Select the themes you want and click Back. At the top-left, click respring and after respringing, you should see your theme appear.*
Note: Winterboard uses a hierarchy, whatever theme that is selected and on top will override other themes that conflict with it below. Move the themes up and down in Winterboard to adjust the hierarchy to your needs.
