Listened to you guys and need help.

Okay, so i bought a mirror less camera Olympus EPL-1. Now, so far i took some decent shots, but i still feel like i have no idea what I'm doing lol. Is there a good book to read on photography or even online tutorials. Also, one thing i love what i see a lot of you guys are producing is amazing bokeh and depth of field with distant objects (i have to get close to likle my dog). I would love to know how this is achieved? Do i need better lens, i have the one i believe comes with it, M.Ziuko ditigal 14-42mm. If anyone wondering why i didn't get a better camera or DSLR because of budget to be honest. Thanks for anyone who can help me.
