In reply to stevemarkperry:
I think this is spot on - whilst going climbing is obviously the best way to get better at climbing, a bit of focus will help no end. As a beginner, you're at a point when can easily develop good (or bad) habits - so as others have mentioned, a few "drill" type exercises in your warm up are ideal, just make sure to keep them fresh and stop them getting boring, but the ones you've suggested are excellent starts.
Another thing to turn into a habitat is route planning and reading - get used to looking at boulder problems and planning where the holds are, what moves you might do etc. And then review afterwards - why did you do well? Why did you fall off? Really easy stuff, but good to get into the habit of - even if you just have a little think over in your head.
The same applies for routes - although you can't plan every move, you can split them into easier and trickier sections in your mind, which makes trying hard things a little less daunting.
Anyway (went off on a minor tangent there) stick with the book (its good) and take the opportunity to develop good habits early - it'll make it far easier to progress through grades both now and later on!
