You should get the jonin medal first. It allows u to go through the game quicker in a way and makes u stronger. ud have 4000 gold then, I would spend it on magatama and the packs offered with tools that will boost your power. Buy seal scrolls in 10s so u can do draw ten and definitely get a rare ninja. If youre on a brand new server take adavantage of the packs that they offer.

All in all, buy thing that will make your power number go up, buy seal scrolls in 10s.
