Im a shorter golfer with un satisfactory length off the tee and wtih irons, help?

I am about 5'4 in height and hit the ball a decent distance but not enough to really put my self in good positions with longer courses. My drive will go about a max of like 260 250 but i really could use more off the tee as well as my iron shots, my iron distances are about as follows L-60 S-80 G-110 P-130 9-140 8-150 and then increments of about 10 going through a 5 iron then 4 and 3 hybrids and a 3 wood. I just don't feel satisfied with those distances and feel that I could do alot better but is it impossible because of my height? Help Please!!!
