Absolutely... but I'm going to have to put a slight limitation on it until you ahve time to 'reflect' on what you have learned and recieve some training. If you plan on putting points into search and disable device, then you'll have to put the points that you would put towards disable device to the side until you got some training. There are certain skills if you are just getting that are just to hard to explain without training, and disable device is one of them... especially with the level of expertise that rogues have. Other abilies and skill may also have to wait. As for saving throw bonuses, hitpoints, existing skills, BAB and most other things, those changes can eb made right away.
