My wife is 4'11 and 125# and and skis 163s. You might do well with something in the 160 cm length.
Also if you haven't already bought boots, you should spend some time getting properly fitted boots. Ski Center in DC does a good job. You will get better service if you go some time during the week.
I would second a recommendation of the Volkls. Very nice product.
Please, please, please don't spend money on skis if you need boots. Also, don't be too afraid of getting a ski that is too "advanced" for you. As an intermediate, it is pretty hard to buy a ski that is too much for you to handle until you get very close to the highest performing skis.
