Well, I'm totally a newbie here too, but I'm very excited because I can kinda help you with this! The valves you have on your bike(same bike I just bought 3 days ago) are most likely presta valves. I went to Wal-mart and found a few pumps that have presta valve adapters with gauges. The problem is that my tires take 80 psi minimum and those pumps only go to 70 psi. I would check at a bike shop or a sporting goods store. I would bet that they have pumps with gauges built in.
Hopefully I helped
If not...I've only wasted about 20 seconds of your life
