For a QT tank bare bottom is the way to go. Lass places for parasites to hide and seeing as how you'll be dosing medicine into it more so than your regular tank the bacteria argument isn't as valid here. It's good to give the fish something to hide in. PVC pip will do for a budget. Remember if this is a QT it doesn't need to look flashy.
+2 on the 10 gal with a HOB filter. The fish won't be living in here, it is just a temporary stay.
