I'm going to slightly disagree with the other respondents.
First, none of those will give you a larger scope, nor is there any significant probability of them improving your chances of getting a job or into a medic program.
That being said, they're not entirely useless....Well, ACLS would be useless for you (Except inasmuch as it might potentially allow you to anticipate your medic's needs, but honestly, you'd be better off just printing off a copy of the algorithms and memorizing them.).
PALS: I don't know for sure about PALS, since I've always done PEPP, but PEPP at least has some relevancy to BLS, a whole bunch of it deals with stuff you're not going to be able to use, but some of it is useful. Perhaps someone who is familiar with PALS can chime in here.
EKG Interpretation: If it's a EKG from scratch class, then I think you might find some value there, if it's an improve your EKG skills class, not so much. As with pretty much everything else, the key to getting good at EKG interpretation is to do it a bunch. You're not going to be able to diagnostically interpret the EKGs while you're on calls, but assuming you have a halfway decent medic, they should be willing to print off strips for you to read after the call is over, and walk you through the correct interpretation. As I said, this will have 0 impact on your pt care while you're a basic, but it will make your life easier when you hit medic school.
To continue: You might want to look for someone offering GEMS or PHTLS (or one of the equivalents), again, in each of them there's a bunch of material aimed at I/P, but there's still good stuff for basics.
Moving off the carded courses, there's almost no CE that won't offer you something, any time you can, take CEs being offered in your area. Remember, CE isn't about recerting your license, it's about being a better provider.
