Non-donation or donation, the stats RARELY differs. Especially since we have vote fsets, you can easily gain a set with donation stats. The only thing missing would now be the valkyrie weapon and Urds(int acc with slots).
For stats, i can give a rundown.
STR: around 50-100, no more no less. This is just for the weight. This is the base stat, ignoring the bonus ones from the sets since those do not give weight. In short your stat should look like 50+ 12 for example that you wanted 50 str just for the weight.
agi- until you get 195 aspd, add dex first.
Dex- 150 TOTAL STAT including the bonuses
Luk- none
INT: people will always put rough numbers here but I'll give a different one. If you can get 2x FBH shoes and would be able to farm for Urds(to have siroma/imp cards on the acc for bolts) get around 12k matk-14k matk. It does not matter if the int ends in 0 unlike STR.
VIT: whatever is left but make sure it is minimum 100. If you follow niemono89's suggestion of minimum 80 vit, any skill that stuns will stun you.
Just quest the weapon for the bio, it is good enough to last for a while. Vote to get at least one minimum vote forsaken set, THEN vote for the biochemist infernal cloak. Farm and get yourself a quest aura that gives +20 stats. Farm for the gauntlets(INT) for now.
For the cards, 3 kiels is always needed for the spam. 2x fbh on the shoes is the normal if you went for the bolts, however the normal green ferus cards or antique firelocks will help you a lot at the start more than the fbh. For weapon cards, again ignore what niemono89 said, the weapon cards that give INT gives so little INT that it will not raise your acid demonstration damage to be noticeable. Equip cards that would be useful for you. Need some form of defense against melee? Stormy Knight card would help. People kept using GTB on your bolts? Use dragoon warlord card. Use valk randgris to have people get their buffs dispelled. Use thanatos maero card to slow people. The essential card i would say is Phreeoni card. you need to +100 hit to actually hit people with physical attacks. The reason for this is for you to be able to use cart revolution, to push people off their pneumas so you can spam acid demonstration on them.
