Raynoxes are very good and you'll have so much fun using them. The thing about using a 50 is you'll need to get quite close, and dragonflies can be quite flighty.
There is not a shortage of great value for money, used, good enough quality manual macro lenses (ie vivitar 70-210 is easily available on ebay) that will let you shoot from a bit further away. It's actually quite hard to find a really bad macro lens
Maybe just play with the Raynox for now and do some homework in the meanwhile to look up shots you'd like to use and see what the eq is that's used for them. Flickr is quite helpful for that.
Be careful, this is how we all started

If you have a telecentric lens then this doesn't happen, but not many of us do. Good software will handle the change in size, have a look at zerene stacker. I wouldn't recommend moving bellows extension length during a stack but move (camera + bellows + lens) all on a stage. What you don't want to do though is move the specimen relative to the light because that changes the light during the shoot which isn't great.
Lastly, I have a huge site about all this - http://extreme-macro.co.uk/ - it is zerene stacker stacking with stackshot. Different tools but similar process to how you describe it.

Couldn't resist having a go
Quick Photoshop light pollution killer...
* Duplicate the image (Ctrl-J)
On the top layer do the following:
* Use Gaussian blur with a very large value (e.g. 50 pixels)
(You should see a completely smooth and featureless image)
* Change the layer's blend mode to "Difference"
(You can dial the layer opacity back a bit to let a bit of feature through)
* Now tweak with levels if required
Voila! (Worked a treat on the West Yorkshire image)
