I suggest if at all possible go along to astro club observing night or better yet a star party and look through as many EPs as you can. My preferences in EP selection are not likely to match yours. But the basic idea to have one low power EP, one general purpose DSO EP, one somewhat higher power DSO, and several higher power planetary EPs is pretty general. To summarise more clearly/succinctly:
Go for exit pupils of 6mm, 2mm and 1.4mm for your three lowest power ones (these are rough rule-of-thumb numbers, not set in stone), and have several more in the 200x-300x range. (Whether you achieve this with individual EPs or combination of EPs and barlow is up to you.)
Good luck.
Note:
Exit Pupil = Eyepiece Focal length divided by Telescope f-ratio
