How would getting wood there be difficult? Just use portals to bring as much as you need from your home storage or grey-dwarf farm/blood magic autotrainer.
As to stone- you're only going to be able to get to Ashlands initially by boat, so just bring 2 iron with you for a stonecutter and go to town. More sensibly you bring all the iron, copper, tin and bronze you need for your desired base facilities, and if you're feeling paranoid about your portal catching fire then bring a load of black marble with you too to construct your starter base till you figure out what's what.
Regardless of anything else, even at original release it wasl the best 20 bucks you can spend on a game if you have any interest at all.
