I bought 2 new MH bulbs for my tank over the weekend. I was going to swap them out tonight, but have been told that I should do one tonight and then the other like in a week. Is this common practice in changing out bulbs?

Yes. Change the light as gradually as possible. Some people even use a screen over the top for a little while. The new bulbs can be 20-30% (I think) brighter than 12-15 month old bulbs and you don't want to shock anything.
