No it has nothing to do with that. Once you render out your images. Import them into Premiere. In Premiere, go to preferences -> General and Still Images and change the default duration for still images to 1. Now just select all the images and drag them to the timeline. Because the rendered images are numbered (whichever naming scheme you used in maya's render globals), it'll be in order when you drag to Premiere's timeline.

Yes, I'm pretty sure you could use Vegas video as well.
