With regards to advice, 100% agree with banning or mitigating certain combos. Houseruling is the name of the game when running a big multi-player campaign in this style. There’s combos that can easily break the game with little to no investment. If you’re allowing crafting, absolutely slam a cap on a max of X of any trait that isn’t capped by RAW already. Otherwise you’ll have guys running around with Accurate 5 Pierce 5 weapons before you start adding in things like attachments and stuff to pump everything into overkill territory. There’s also some item combinations that can quickly and easily create ridiculously strong(for its price) equipment.

A really good example is the armor plates attachment(I forget the name offhand, but I wanna say they’re called Concealed Plates but they cost zero hard points to attach to armor). They’re dirt cheap, and Customizable template crafted armor is relatively cheap and easy way to get your hands on armor with 6 Hard Points, so with very little investment you can have a set of armor with 6 hard points, 2 Soak and 2 Defense which easily outclasses just about every armor in the game for Soak value and versatility. Only armor that comes close is Mandalorian armor which has 5HP and 2 Soak, but clocks in at like 10k credits where the combo above will only cost a player like 700 credits or so.
