I'd definitely start on the t2 miner. Obsidian and the granite maybe sulfur might be good too. Don't forget you have 1-2 lockers of dolomite and bauxite so you could easily get the titanium and also kick start some super alloy so you don't have to store too much of the lower materials. Base is going to look really interesting and look forward to seeing how it turns out but you definitely will need windows too!
