Shelter before Fire
I suggest that unless you are very good at building a quick fire from materials immediately at hand, concentrate on building a shelter first. Should something happen that you cannot start a fire and bad weather rolls in, you may find yourself wet and cold with no shelter.
Once the shelter is finished, you can build the fire and have the shelter available for a quick escape out of the weather. This is a judgement call as you may need the warmth to help treat hypothermia victims or have an opportunity to send a signal. However, if you are high and dry, build the shelter first then spend time on the fire.
Also, don't make the shelter too big, your body warmth is your heat source so you don't want too much air space to have to heat up. Keep it to 3 persons or less to a shelter, rotate into the middle so each gets advantage of having that warm envelop for a brief period of time.
