In your case... just go. No worries if they were done by a reputable shop as per your post. You should carefully inspect the tires if they have any age on them.

I don't pull mine 1000 miles a year at this point, and have never re-packed them. I jack them up at the beginning of the season, one wheel at a time... check for bearing play and any noises or rough sounding bearings, and then (as per instructions) grease the "easy-lube" spindles while spinning the tire. I don't see the need for a hub packed FULL of grease, so I use a needle to lube the outside bearings at the same time. I have to remove the dust cap for that, but I can get the needle past the washer just fine. I don't remember ever having to tighten the bearings on this rig.
