The one part I can't seem to figure out how to do is to upload the images into a specific collection or set from LR.
Have you taken a look at Jeffrey Friedl's LR to flickr publishing plugin? http://regex.info …om-goodies/flickr/publish
That's what I use, as opposed to the stock flickr publishing service that ships with LR3. Jeffrey's plugin has a feature that allows you to create a new "publish collection" in LR and simultaneously choose which set(s) and/or group pool(s) you want that publish collection to publish to in flickr. He has a very comprehensive user manual for the plugin which you can find on the page I liked to above.

And BTW what is the difference between those 2, sets and collections?
A set is a group of individual photos on flickr. A collection is a group of sets. You would typically use collections to further organize your sets. For example, if you had a set that contained images of family, another set that had images of strangers, and another set that had images friends, you could create a single collection called "People" that contained each of these three sets.
