SmartLipo and/or liposuction together would be a good option for reducing the pouch that you have.  These techniques will reduce the fat/bulk and also stimulate the skin to tighten.  The main question is always, how much will the skin tighten.  This is an important question in getting you the flat belly that you desire. An examination to assess your skin texture is the best way to determine this.  Best to schedule a consultation with a qualified and experienced liposuction surgeon.  Best of Luck

The best option for your lower eyelids is to place some filler into the sunken areas.  This can be done carefully and in an exact manner.  There should not be any change to your eye shape.  Juvederm or Restylane are good choices.  These hyaluronic acids can also be dissolved if you don't like the effect they provide.

Most patients will reach maximum tightening at 2-3 months post surgery.  Although there may continue to be some more tightening happening, it is usually minimal.  Some procedures that can help promote additional skin tightening post lipo are  external devices that use radiofrequency energy such as Pollogen, Pelleve or Thermage.  These devices help heat the collagen and encourage further tightening.  I would look into these treatments if you want to get the maximum tightening possible.

Some physicians will use a more dilute solution when injecting under the arms, hands feet, etc. for hyperhydrosis, but some use the same dilution as the face.  

I, myself, use the same dilution but inject very small amounts.  The most important factor is the number of injections given so that all areas will be covered and secondly, placing the injections just under the skin so that they are at the same level as the sweat glands.

You could choose either option, but I believe you would get superior results and a better overall aesthetic appearance if you chose the mini-lift. It is true that fillers are easier and quicker in many ways, but my concern is that you would have to use so many syringes to address your cheeks and jawline area that you may easily wind up spending almost as much money as you would for a surgery.  The mini-lift would help reposition your cheeks to a higher, natural position and would address the jowls that you mentioned. The overall effect would be a sharper more defined jawline and a more rounded youthful face. A small chin implant would enhance this procedure and give you more projection and balance in the chin area, but this is not an absolute necessity.  This is something best discussed with your surgeon in person.

Fillers would hide or disguise your jowls but would also add more weight or volume to the lower part of your face.  You could lift your cheek with more volume (fillers) but unless you use fat transfer or possibly Sculptra, you will be replacing these fillers again in 6-8 months.
