Leawood Liposuction doctors

That bulge is actually muscle - the external oblique.  It will not go away, and if it did, your contour would look abdnormal.  Even extremely lean people have a muscle bulge here.  Hard to comment on the surface irregularities without seeing your before photos.  Certainly any irregularities appear quite minor and your result looks quite acceptable.

It depends on what you mean by a beer belly.  If you have a protuberant abdomen with minimal fat between your skin and the underlying muscle you meet the usual definition of a beer belly and are not a good candidate for liposuction, because liposuction can only access subcutaneous fat - not the "visceral" fat inside your abdominal cavity.  This internal fat can only be reduced by weight loss.

When you diet, the fat cells shrink but they don't go away (the number stays the same).  Only liposuction reduces the number of fat cells.  Ironically, if you are too thin, it gets harder for the surgeon to suction out the fat cells (we have to be careful to leave a cushion of fat between the skin and underlying muscle).  So really there is no need to go on a crash diet, and these diets are notoriously unsuccessful (you are likely to put the weight back on in short order).  Also, you should be nutritionally healthy at the time of surgery.  Not a time to restrict calories or protein because you need these for healing.
