Just got back from vacation, took another stab at it, and had a lot of success! - Thank you KAD for the suggestions, that definitely helped me get started.
All options menus work now except for one. (I'm hoping someone can point me in the right direction here as everything I try fails.) I can't seem to get the options menu that lets you choose how you're browsing your files to work (Thumbnail, List, Preview). It just doesn't appear at all. It doesn't render the OSD useless, but it would be nice to have.
I couldn't get the existing style of options menu to work on 1.03 so I've reverted to the style of the default OSD, just with picto icons in place (see below).

I believe that Pandora and Deezer options are in place properly but can't test Pandora as it's not available in Canada and don't even see an option for Deezer when navigating the OSD. Mediafly also works properly but could use a little bit of formatting to make it look prettier. (Not really something I'm good at so I may leave it as it is usable right now).
If someone could please test Pandora and Deezer for me and let me know how it is, then once I figure out the file browsing options menu thing, then I can apply these to the other versions of Picto as well and I'll post them here.
Thanks again everyone for the help!
