Are there any discernible differences between these three color models, or do they read the same values?
I'm asking because Gimp uses HSV, but Paint uses HSL, and I am not sure of their differences. I also do not want to use online HSL sliders to find my hues.

There's a whole bunch of different methods for calculating the Lightness/Brightness/Value/Intensity/Luma...or even define them, and I don't think you can be 100% sure what method a program has assigned to that factor, whatever the character. It's a bit of a mess I believe.
http://en.wikipedia.org/wiki/HSL_and_HSV - Wikipedia on HSL-HSV
Personally, in my Grafx2 scripts; I use HSL where L = Lightness and L = (max(R,G,B) + min(R,G,B)) / 2, as well do the program I think. But note that changing Hue is a "destructive" operation, as it may offset the Brightness/Lightness of a given color.
http://goto.glocalnet.net/axe/dtb12/#pal_adj_huelight_pal - Example of Hue-tweaking problem (Check Palette/Adjust/HueLightness if it doesn't jump to the right place)
That's why I for quality operations use what I call HSB, but here B is real "Perceptual Brightness", rather than just another term for Value (yes, I've made it even more ambiguous :/). With this I can provide the option to maintain the Brightness when you tweak the Hue (as Green is brighter then Red is brighter than Blue, things normally get screwed up when you change the Hue of a Palette/Image without Brightness correction).
Now, I'm sure that this did very little to clarify things for you. It's just so confusing that I have to use opportunites like this to remind myself of the basics, haha!
And, yeah. Don't use Paint. Ever.

I actually never used Paint, and I don't intend to because of it's heavy simplicity.
I'm thinking of converting to Grafx2 just to use your scripts. They're just so enticing; I just need to figure out how to use it.
