build a pickaxe(must have to mine silver, you can do with antler pickaxes until then) and stonecutter first(needed for your bench upg and building stone stuff). then build upgrades for your benches(new crafting options are always nice). that's the top priority.

if necessary get armor(unless you're confident that you'll be able to survive without it, for example i prefer to have my lvl4 troll armor and bronze buckler and save resources instead).
you can still sail on a karve, so getting longboat is not a huge priority. and you don't need something better then bronze axe to chop any trees.

ps: don't forget that plains tier armor require iron to craft. so save some for the moment you'll get there
