It sounds to me like the lack of non combat stuff may be down more to your party than the system. Have played in parties like that! In fact our previous Shadowrun we used to spend far longer planning a run than performing it, but the current campaign just goes combat first! Same players, different approach. I think so far our Star Wars party has had two fights in a dozen sessions.
I know what you mean about rules in different books, but at least here it is pretty easy to make new items. Pretty much any item is either "tools for the job", "gives bonus dice" or "removes setback dice", depending on it's role, I suggest.
I wouldn't want to cite Shadowrun in a conversation about rule clarity! (Was GMing it last night!)
