A few questions about adsense ads

[marka2010]

1.When should I filter the low-paid ad such as 0.01$? Is it suitable If my website's traffic is not very high such as 1000 pv per day?

2.My sites have two languages, one is English, the other is German. Can I change it? Let English site show English ads.

Thank you if you take a look at my topic.
