Others know far more than I do on this sort of stuff. However, I would ensure that different urls that result in the same content are differentiated by use of the query part (i.e. text following?).

Unless this cannot be achieved for some technical reason, this approach is likely to cause the fewest problems in the long run.

You might consider placing parameters after a # char. This would have the advantage that spiders will not keep crawling the same page, etc. You would have to do some research on this.
