Get the RAM regen in combat perk ASAP.
Early on you won't really have the money for the high base RAM decks, so get one with a fast regen rate.
RAM is your mana, and buffer size has to do with the little puzzle that lets you get money and crafting components. The perks for crafting your own quickhacks is helpful too, but you can just buy them if you don't want to deal with it I think.
I always keep ping and short circuit slotted. Contagion starts out trash and ends up godly.
General advice, skills are limited to their governing attribute, you can't go over it, so if you have 6 INT, you can't get breach protocol or quickhacking over 6.
Unlike most cyberware, I don't think cyberdecks have an attribute requirement, so the only issue is money. Every quickhack you upload gives you exp too, so spamming ping and distract enemy on the vending machines, even if no one is around will give you exp.
