I'd definitely make drainage holes. I tried planting various things in a planter with none and the rain just sat in it and the plants died. Also, as it's wood, I probably would line it, to help preserve it/protect it from the moisture. I've found that conifers are really thirsty so that might be something to consider. I was researching heathers to buy recently (on the RHS plant finder website as always). There are some that don't mind acid or neutral soil. So I wrote the names for those down and managed to get both at our local garden centre. Most will need to be in ericacious compost. I think I'd just go big and blowsy, cheap and cheerful, chop and change according to what's out at the time so you always have a colourful display in it. Experiment. But we all have different ideas.
