Here's a list of my house rules. I highly suggest that all of you use them.
1) One arrow on person at all times. No more.
2) No 5-foot steps.
3) Three partial actions make a full-round action.
4) A full-round action is 7 seconds, not 6.
5) A Wish or Miracle spell can grant any of the following with a single casting: 10 feats, +5 to BAB, a template that does not actually modify your ECL.
6) Mind Blank protects against everything, even fireball.
7) Mirror Image can be used to create a dancing chorus line that forces your victims to roll 5d100. A result of 2 or higher means that your victim can't attack you that round, that you can flank them with a +25 bonus to attacks, they lose their Dex bonus, suffer a circumstance penalty to AC equal to 8x the number of images you have.
8) Drawing an item from a HHH is a full-day action, unless you know exactly what pocket the item is in, in which case it's a full-day action minus 2 full rounds, which is 14 seconds, not 12.
9) You can sneak attack only once per round (the rogue is broken).
10) Fighters get 2 bonus feats every level (the fighter is broken).
11) The Ranger's favored enemy bonus is multiplied by 5, applies to attack rolls too, and can harm even creatures immune to critical hits, and there is no range limit, and finally, they get a bonus feat every other level (the ranger is broken).
12) Sorcerers can cast twice as many spells per day as shown in the PH (the sorcerer is broken).
13) Wizards can't cast spells at all (the wizard is broken).
14) Clerics get a d2 for hit die (the cleric is broken).
15) Paladins aren't changed at all (the paladin is perfect).
16) Druids can no longer wild shape (it's a stupid ability).
and finally
17) The bard is no longer an available class (they suck anyway).
YMMV.
