The following are a few links to give fans a look at the Chargers.
I would be remiss if the first site I mentioned was not SB Nation's excellent Chargers blog, Bolts From the Blue.
Nobody talks better smack than Al of Bolts Blog.
The official Chargers website has plenty of stats and information on San Diego's players and coaches
The San Diego Union-Tribune is the main newspaper covering the Bolts.
Bolt Talk is a huge Chargers fan forum with its own podcast.
Charger Fans is another forum.
