I would say absolutely. You could use the app GoodReader on all iPads, Setup a GoogleDocs account for your office and give the username/password to all employee's. GoodReader would then let everyone download/upload any files they want in google docs. basicly Upload file to google docs and and it would show up in every one elses GoodReader.
And for meetings, you should check out GoToMeeting. You could hold a meeting and everyone can attend via computer or iPad(they have an iPad app). The GoToMeeting app on the iPad lets people attend over the internet so they can be anywhere and still hear you, view your presentation and even talk back if they want using the ipads built in microphone.

I think you should get one iPad to really get a hands on feal for it to make sure it will work for what you want to do before jumping out and buying a bunch of them..
