Here's a good guideline of priorities to work on for your first group of pages:
 * Main page
 * Wiki topic page (article about the book, game, show, etc. the wiki is mainly about)
 * Main characters
 * Main locations (fictional or real)
 * Most notable antagonists (main initial bad guy, mentioned rivals, mysterious monster or force, etc.)
 * Most notable items (special artifact, main character's weapon, well known monument, etc.)
 * A glossary or guide to terminology, if necessary (good especially if there alot of new terms introduced...)
 * Main cast members or primary creator/author...
 * Book series, expansions, or episode guide...

That should get you to 20-25 easy. Depending on how much source material you have, getting to 50 pages should be a snap!

Going it alone will be much slower, so try to get other fans involved as soon as you can.
