How would you clean up this file?

The link at the end of this message is to a 68 second mp3 file of a 
dawn chorus I recorded last Sunday in Jefferson National Forest in 
southwest Virginia.  I am new at nature recording, and wanted some 
suggestions as to how to reduce the low end rumble, hiss, and if 
possible, some of the insect noises.

The attached clip has most of the challenges I'd like to address:  

1 - Thoughout the recording there is low frequency buzzing from 
insects.  Can this sound be filtered out or diminished without 
getting the "blurby" sounds I sometimes get with a filter?  Can this 
noise be reduced without decreasing the quality of the other low 
frequency sounds?

2 - There is some high frequency hiss in the recording.  How would 
you reduce this without substantially changing some of the high 
frequency sounds, like the bird call from 1:05 to 1:08?

3 - At 1.5 seconds and again around 18 seconds an insect flies by - 
is there a way to decrease or eliminate this without substantially 
changing other low frequency sounds, like the "gunk, gunk" calls of 
the green frogs in the background?

Generally, I am looking for some guidelines as to how to approach 
the task of post-production - what filters, noise-reduction methods, 
EQ, etc. to use, in what order, and how to do this without making 
the result sound too sterile.  Any advise would be greatly 
appreciated.

FYI, I used an HBB Portadisc and MKH 30/40 to get the recording and 
will be using Adobe Audtion 1.5 to do any post stuff.  The only 
thing I did to the attached file was to mix the MS to XY using 
Audition's channel mixer at the default settings and saved the file 
as an mp3 to save some space.

Thanks in advance to anyone who can give me some suggestions.  My 
hope is that the more experienced of you can educating the less 
experienced of us in the science and art of what to do after you've 
finished recording.
