Post a picture then we can tell you... actually if the pads are silver it will be tinned, copper color if not.
Most commercial PCB houses will tin pads as standard. If it is a board you or a friend have etched/milled then it probably won't be tinned.
Tinning the pads isn't a pad idea, just apply a tiny amount of solder, you want to keep the pads fairly flat for soldering SMD devices. You can just run an iron over the pads with a soldering iron loaded with some solder. Solder wick is useful for removing excess solder.
Or just not bother as nophead said the soldering part is the same technique :)
