Yes, basically. I'm far from knowledgeable on this subject. There are many different techniques.
One thing to consider is that some atty's come with a primer on them that has to be blown out or burned off. It won't hurt you, it just doesn't taste good. The ones I mentioned above don't seem to have that issue.
What I do is to drip about 4 drops, one at a time (allowing each to soak in) onto the bridge of the atty. It may take a drop or two more initially, depending on the size of the drop and the wicking ability of the atty. The bridge is the metal/mesh-y looking part you see inside the atty. Then pop on a drip tip and take a drag. You'll be able to get a few drags out of it before you get a metallic burned taste, which means you have a dry atty, which you don't want. You'll get the hang of it.
When I want to change flavors while testing, I take the atty off the battery, take the drip tip off and blow hard through the mouth end while holding a paper towel at the battery end, a few times, until no more juice comes out. It can get a little messy, so paper towels are good to have on hand. This gets most of the excess juice out. Then I start with another flavor. I do get some flavor "overlap" but after a couple of drags the new flavor takes over. Beware that some very strong flavors (wintergreen, for example) are very hard to remove from an atty....
Because I only use the atty's for testing and they sit for a while, I clean them after each testing session. I use vodka - mainly because I read about it somewhere and it's what I had on hand (everclear, too, I hear, as well as a vinegar/baking soda combo, or just vinegar.....). It works for me. I wouldn't use rubbing alcohol. I soak them in a little container with a cap for an hour or overnight, swish it around, blow it out, rinse with water, blow that out and let it air dry.
Again, I'm an amateur with atty's. There are many techniques for using them and cleaning them that are good. I would recommend looking in the Atomizer Issues sub-forum to get ideas. You may find some methods you like better.
One more thing: I do recommend getting at least two atty's so you have a backup. I got three since they are so cheap at the above source and my shipping was only $2.25.
Good luck!
