Yes. A goalkeeper can dribble the ball back into the penalty area and pick it up. However, this is not the case if the ball was passed to him by a teammate (back pass), or if he has (for example) thrown the ball outside of the penalty area only to dribble it back in (double touch), or in any other case specifically disallowed by the laws.

If his team has substitutions remaining, they may substitute in a new goal keeper for a field player. If not or if they choose not to, then a field player must become the goal keeper.

A PAT is one point regardless is drop kicked or kicked off the ground. Same for a field goal ... a field goal is 3 points regardless of how it is kicked.
Every football field had a integer. The integer is there for the score keeper.
If the goal keeper is sent off they may not be substituted for. The team has 2 choices. They may name a player, who is already on the field, as the goal keeper or, if they have substitutions remaining, they may substitute a player for another goal keeper. One player on the field of play must be the designated goal keeper. Play may not continue without one.
