I've got a rough progression path for my character. I'd grind up money and when it was comfortable to do so, move to the next stage. It was;
Sidey > Learn game > Eagle > trade and missions > Viper > bounty hunting and piracy > Type 6 > learn advanced trading and do some smuggling > Asp > exploration, missions, advanced bounty hunting > python > heavy combat, missions, influence changing, piracy. No intention of trading/selling my ships in between those stages, and also collecting various ships to kit out for specialised roles. Money will come as it comes. Set smaller goals and advancements then let the dice roll. More fun that way ;-)
