Make sure you set the frame padding properly or you wont be able to import them properly. Frame padding just adds leading zeros to a frame number so that packages like premier can import them:

e.g.
frame padding = 1 gives frame1, frame2, frame3 etc.
frame padding = 2 gives frame01, frame02, frame03 etc.
frame padding = 3 gives frame001, frame002, frame003 etc.

Unless you're going over 1000 frames set it to 3.

Dont render as Jpgs as they introduce artifacts into the render. Use Tga's or Tiffs (I always use tiffs) any app that puts image files togther should be able to handle them easily. The only problem is that because the tiffs or tgas are lossless compression then they ca get big in terms of file size: 1.2megs for one 720 x 576 tiff is pretty normal.

Hope this helps
