I second the look at hanger alignment if the smaller three cogs' shifting and operation is of "no leeway". You can buy a tool to gauge the alignment and the cold set adjustment of it (steel frame preferred) for what it would cost to have your LBS do it three or four times. If shifting is great on the larger cogs but gets picky on the smaller ones, alignment may be your issue.
Also check for a worn rear derailleur, jockey wheels too. I was shocked to find this when isolating shifting problems on my commuter and found the upper pulley wheel able to tilt off pivot axis by 15-20°. Its bushing seat was worn out and away from the pivot outward, Check the B adjustment screw setting and the operating drivetrain not running with the upper jockey wheel in contact (but for the chain between them). Slight hanger alignment problems seem magnified by that although mostly a problem in the bigger sized cogs.
