If you're a wizard and you get buckets of feats, spend one of your ordinary (3rd, 6th, 9th, etc.) on point-blank and precise shots. Heck, if you have a decent dex (and are sufficiently afeared of close combat) you should probably take rapid shot too. It improves a low-level wizard's combat effectiveness tremendously.
I've got a custom class character (my DM's world, it's great and crazy) with point-blank and rapid shots. I'll get precise soon enough, and focus on casting rays, and Melf's Trippy Projectile in combat.
