I think this is marely a matter of programming style in your case. If
you like to use OOP use it. If not, don't. It doesn't seem to me that
OOP is necessary to anything you just mentioned. Don't let the
possibilities slow you - they're there so you can use whatever you
like, not to flood you with too many options.

Good luck,
Gal
