Narrative:

After we loaded up the passengers on the aircraft we were notified of a ground stop into our destination. During the initial set up of the FMS we were able to put the flight plan in except for the arrival. As a result of this I used the arrival plate to manually input one fix at a time for the arrival. After that the flight plan appeared to be correct. When the ground stop was lifted we had an uneventful start up; taxi; and initial takeoff roll. Promptly after the 'positive rate' and 'gear up' call outs; tower gave the hand off to center and so I flipped over to departure and checked in. Also at this moment we noticed a few icas messages flash for a few seconds then go away. These concurrent series of events distracted me and I missed bringing up the landing gear. I continued the normal flap retraction schedule and profile. During the climb I noticed it was a little louder than usual. Also we had a 'check reserve' message come up on the FMS. I was focusing on the complex departure; reviewing the flight plan accuracy; getting ATC clearances; and trying to trouble shoot. I even confirmed the flaps were up; speed brake not deployed; APU off; and was looking for abnormal ecais messages. Since there was no ecais messages flashing at me I assumed that there were no issues with the aircraft configuration. After we were cleared direct we discussed the situation and assumed the worse case scenarios; such as fuel leak or structural issues. At this time we decided to divert. I notified ATC that we wanted to level off and also go to a divert airport. Enroute to our divert airport we continued to trouble shoot the situation and that's when we noticed the gear was down. After gear retraction we recalculated our fuel and didn't have enough fuel remaining for the required reserve. We then elected to return to the departure airport to get more fuel. Use extreme caution during distractions. Aviate first; then navigate and communicate. Also avoid fixation. I was so focused on the noise; messages; and FMS that these items caused me to overlooked the obvious.
