If I want midface or paranasal implants in the future, do I need to have it done at the same time as rhinoplasty?

Changing the projection of your midface can change the projection of the nose. I would recommend either doing the midface work first and then the rhinoplasty, or having them done at the same time. If you can find a team of an oral surgeon and a facial plastic surgeon then you could do a combined case.

A paranasal implant simply give more projection to the base of the nose. Cheek implants  are placed directly over the maxilla and augment the entire cheek area  when patients have mid face hypoplasia. The rhinoplasty and cheek implants can be performed at the same time under general anesthesia. For many examples and more information, see the links below
