1. If you mean when taking control over party members, it's been changed. Now player's traits and perks (except Gecko Skinning) don't get transferred to controlled critters. 2. The levelling requirements of party members are in party.txt. Taking Sulik for the example: That means he only starts to have a chance of levelling up when the player reaches lv 6, and the roll (random element) for his levelling will also occur at lv 9, 12, 15, etc. The option in ddraw.ini removes the roll, so he'll always level up when the player reaches lv 6, 9, 12, etc.
