Great start!
Some helpful (I hope!) tips for photography:
If you want it not to focus on the paint pots in the background, remove the paint pots! Your camera is trying to autofocus on what it thinks is relevant. Remove anything that it might consider focusing on instead of your models.
Next, use ambient lighting, not flash lighting. Light that is being reflected off walls or scattered through something with an uneven surface can usually mimic this.
(Edit: Looking at your other thread, you have some great pics there with a white BG! What gives? Too lazy this time?! )
