Ribbon eligibility for a new LT in the Reserves

I commissioned April of last year, was placed on IRR status until I got picked up by a unit in February this year, and so far I've done two drill weekends and went on orders for four days of training in a different state. Another LT who's been around for a few years told me that simply by joining at this time I was eligible for a number of awards, including the National Defense Service Medal, the GWOT Service Medal, and the Army Service Medal. I have refrained from pinning these on because I'm a little doubtful about my eligibility. I looked up AR 600-8-22 (pgs 24, 31, and 65 pertain to these three medals), and I at least do not seem to be eligible for the third of these, as I have not yet attended BOLC. Might I be eligible for the other two, given the information I've provided? Are there others I might be eligible for at this stage? Obviously some of them will come in time, but some folks are urging me to make my ASUs more colorful.
