Dont worry! if you will practise it will come easily! if you want a good song to listen what you are supposed to do - listen to "you shook me" / led zeppelin
Now about the chords progression...
basicly in the E scale you play
E A E E A A E E B A E B
you can convert it to any scale though E seems to be most comfortable
A very helpful thing you can do is to record yourself while playing the rythm and then to playback it and to improvise over the scale
(i'm talking about pentatonic scale all the time) Basicly dont try to stick with these chords , try to be imaginative (this word is exist right ?)
if you want some nice rythm guitar riffs for the start you can drop me an e-mail
