You can do that if you want to. Anything that can supply 12v DC will work. I just used a old wall wart power supply from a linksys router that was 12v 500ma (more than enough for what I need). It was free cuz I had it but it also may be cheaper to buy one then the transformer and PS setup you are talking about. You can get one for like 7 bux on amazon.
You may even have a few laying around the house from and old router or phone charger. If you click this image and look at the full size pic you can see the writing on is saying its 12v .5A (500ma) and it tells you the polarity on the post. You can then note which side is positive and which is negative and use a continuity tester to see which wire is which. The just cut off the connector and wire it straight up.
But adding another transformer and PS should work fine if you are more comfortable doing that.
