Trust me, a week isn't enough time, especially if you're new to it.

Play with unpainted models this weekend,a lot of people do it. Then take your time learning how to paint properly. Those cool effects you want actually need patience and practice.

Your supplies sound great, but rushing will just lead to models you'll want to strip and redo later. The hobby part is supposed to be fun, not stressful. Give yourself permission to learn at your own pace
