wks and wps files "should" open in Office for Mac or Pages
On the subject of Boot Camp.
Boot Camp does partition the hard drive and allows you to install a copy of Windows, XP SP2 and above, onto that partition.
You cannot use Windows and OS X at the same time, Split Screen, because OS X is not running when Windows is, and Vice Versa. When booted into Windows, your Mac is a Windows machine. No sign of OS X.
To do the equivalent of the split screen you would need to run something like Parallels or VMFusion. These two applications allow you to run Windows as a virtual machine, alongside OS X.
It even allows you to drag and drop from Windows to Mac and Mac to Windows.
Installing Windows without a browser is not possible, IE is built into the system and cannot be removed. As long as you have that ethernet cable attached to your iMac, your computer, no matter what OS it is running at the time, is on the internet.
