You will also need a bunch of other things. To really get the benefit of automation in SF, you'll need the enterprise version. Then there are Gmail plugins (we use cirrus insight), billing platform integration, etc. etc. Getting SF configured so it makes sense for you will take time and $. There are also a number of little gotcha's, like inability to gracefully deal with email aliases. Might not be a problem for you, but we find that a number of people use vanity email addresses, personal Gmail, etc. to communicate - and SF becomes exquisitely painful suddenly. In short, unless SF solves a serious sales process automation problem for you, don't go there. Ah - also, analytics. You'll want the Good Data analytics on top, especially if you're in SAAS space. Good stuff and greatly increases the value of SF.
