OP:
"...are there any easier strategies you might recommend to make the image look more like a souped-up, artificially embellished promo pic..."
When you say, "the image", do you mean:
(a) this one particular image;
(b) other existing, relatively "straight" images / snapshots that you might want to work on; or,
(c) photos that haven't been taken yet?
If it's (c), the answer is really simple and unambiguous: Find a good pro photographer who has a portfolio that demonstrates he knows how to shoot in a style you like.
Another option is to try to learn enough about photography to reliably knock out images in a certain style, ie, just like the pro photographer mentioned in the last sentence. Depending on the style you want, learning how to shoot in a particular style might be extremely easy, or it might take years. For example, the style of the example you posted is actually quite easy for a newbie photographer to emulate -- getting close just requires two flashes: #1 is an off-camera flash laying on the ground and pointed slightly upwards towards the band and provides the main exposure. Flash #2 is an on-camera flash dialed way down so that it slightly fills in the shadows created by flash #1. This simple setup will get you surprisingly close to the example you provided.
If your answer is either (a) or (b), the answer is a bit more complicated. First, you have to realize that you have to start with a photo that's reasonably close to what you want. As the old saying goes, "you can't make a silk purse out of a sow's ear". The technical aspects of the starting photo that matter may not even be obvious to someone just beginning to do this sort of work. For example, one has to become well versed in seriously analyzing lighting, ie, direction, intensity, number and types of light sources, etc. Assuming the photo you select to work on matches in these ways, then, IMHO, it would be a matter of personal preference as to which of the thousands of plugins, actions, techniques you feel give an effect you like on your starting photo. Deciding this comes from long experience (ie, years) of familiarizing yourself with the all these post processing options. Of course, you could always use the fun approach of just playing around with images. Unfortunately, an undirected approach, while fun and may result in some really interesting efx, isn't likely to be the shortest route from point A to point B.
If you just want to play around with push-button simple efx that others have created, two really good places to start might be Nik Color Efx Pro (part of
Google's NIK collection) and
Topaz Restyle. Unfortunately, these are not free. If don't want to invest that amount of money, there are plenty of free efx available. They won't be as comprehensive or have such a slick interface as the commercial plugins, but they might be a way to get your feet wet. Try
Medhi plugins, the zillions of free "actions" for PS (just Google it), and the hundreds of editors (eg, GIMP) and related efx available through sourceforge, e.g.,
http://gimpmp.sourceforge.net/.

PS - You might have noticed that I didn't mention the various "filters" that come with both Photoshop Elements and the full version of PS. I didn't mention these because, IMHO, they are waaaaay too overused.
