Pine is not a commonly used material in longboard building. Most beginner builders usually use baltic birch, maple and/or bamboo. As for the board itself, camber or concave depends on what you want. Do you want flex? Do you want a more solid grip with your shoes? It's definitely possible to make a board with both, though that is hard to press. As for what's a good shape, take a look at major manufacturers like Rayne and Landyachtz and see what they're making. And for trucks, wheels and bearings, depending on how wide your board is, you could consider 9" or 10" Calibers, 150 or 180 Randals/Paris, cheap bearings and 78 or 81a Flashbacks as a starting point.
