Congratulations on your successful reassembly. When I got my low-miles German imported XT600, I had cable issues you might relate to. First and most noticeable was the sticky throttle. It ended up being a paper adhesive label still affixed to the handlebars, all I had to do was remove the twistgrip and clean the bars off. Yours might have a throttle cable gummed up instead. Second, I had a severely gummed up clutch cable. When i removed it from the bike, i would have to pull extremely hard to get the cable to move inside the housing. It took hours of spraying it with penetrating lubricants of 2 different kinds before it freed up and moved back and forth like a cable should. Once I got these two cables movement freed up, it was a night-and-day handling improvement; no more hard bucking when I would pull the clutch in in 1st gear at low speeds; the bike would rather smoothly disengage, and with the throttle cable, no more lingering throttle, it only acellerated and let of when I told it to.
Long story short, make sure all your control cables are functioning smoothly, it makes a big difference. IMHO.
