Is it better to remove noise before leveling volume or vice versa?

I'd like to apply both the Noise Removal and Volume Leveling tool from Camtasia's 3's "Audio Effects" to an entire audio track.

They work great!

I was wondering whether it matters in what order I apply them.

In case it's relevant, I'm using Volume Leveling to raise the overall volume level.

As with most things audio, there is no wrong order.  It's best to rely on your ear. Try it both ways and see what gives you the result you like best.
That being said, it's often is better to apply noise reduction first. If you reduce the noise before applying other effects, then the noise won't influence those following effects.

Unfortunately, at this time there is no option to apply an audio effect to an entire track. 

You can however, select multiple clips and apply the effect to all at one time.  However, if you make adjustments to the effect that you want to apply to all clips, then you'll have to make that same adjustment on all clips (which you can do at the same time if they are all selected).  If you want the same effect on all of your audio media and your media is similar (recorded in the same environment with the same mic for example),  I would suggest adding the effects to one media, make any adjustments, and once it is sounding the way you want copy the effect (select the effect on the media by clicking on the effect, then use Cmd+C to copy it), then select all of the media you want to apply it to and paste it (select multiple media by holding down Cmd while clicking on the media, then use Cmd+V to paste the effect).

Leif is right, you have to try it both ways. Either way, listen carefully to ensure that the inevitable noise reduction artifacts don't get amplified to an objectionable level.

I would agree with going with noise reduction first.  If you level the volume first you are going to be incorporating those ambient/ unwanted sounds and amplifying them.  Reduce them first and then there will be less to influence when you level the volume.  You can also try working with the audio in a separate application if you want more control over it.  I have used Audacity (free) and it has amplification and noise reduction effects you can use before you bring them into Camtasia.
