Yes, do what Jonesey said you don't have to worry about dragging clips around.
One thing though, when you do your Range Select in the timeline before exporting make sure you drag out the Range Select far enough beyond the edge of the last clip to capture and "tails". Tails are things like reverb effects or MIDI cymbal hits that might extend beyond what you see on screen in the Track View. Best way to make sure you have select far enough past the edge of the last clip is to listen to the end/watch your Master Bus meter. Make a note of exactly what point on the timeline you stap hearing anything and the Master bus meter shows no activity. Then when you do your pre export Range Select extend the selection about a second or so beyond that.
However I usually do all that in a new "Master" project. Essentially I export the whole thing (Ctrl A and then just do the export with the proper settings).
Then I import the resulting Stereo Wave into a new project in Sonar (or another audio program) and trim off what a don't want and leave enough room at the start and end for a nice in/out time. Then it's just a matter of dragging the ONE stereo clip and butting it up against the 00:00:00 start point and exporting.
Of course in that project you can add mastering effects like a final EQ or compression.
Lots of people do that directly in the original project these days but I find it is a LOT easier in a second project. Less screwing around and distractions. It's also easier on the computer to use the heavy duty mastering effects in a one track/clip project without a bunch of synths and track effects going on too.
Cheers.
