wands and scrolls?

[redoubt]

Artificers must use their UMD skill to use cure wands and heal scrolls, correct?

i.e. they don't get free cure wand use like a ranger or paladin.

[Khatzhas]

Correct.
Rangers and Paladins use wands without UMD in the same way that Clerics and Favoured souls do: If a spell is on your class spell list, no UMD is required.

[averathael]

that is very much correct although you should be leveling your UMD skill as you level up
