The best you can do with the contact / web / applications icons is rearrange them in Settings -> Control Panel -> Panels.

With regards to your first point, one would be hard-pressed to find a sheet detailing either the N800 or the N810 without seeing the GUI. However, if you have an N800, you may want to make sure you have the latest version of the OS. Check About Product under the control panel as well. Latest version is OS2008 4.2008.30-2.

You could try zooming out on the browser (Flash content and images zoom, too), or entering fullscreen mode.

"I need 4 running program icons, can I get that back?" Eh?!
If you mean the window list on the left, then I do not believe so. However, the icon on the bottom left corner can be clicked, which will open a more useful menu with open windows and detail about notifications.
