I've been lucky enough to travel to Shetland through my work for the last 16 years; a wonderful place.
For walking and wild places I would recommend Unst in particular; there is a special atmosphere about the place. Do go to Hermaness in the far North West, for the birds, cliffs and views of Muckle Flugga lighthouse. Also the Keen of Hamar near Baltasound; unfortunately in September you will have missed the rare alpine plants in flower on the serpentine screes. In the NE, Norwick beach is beautiful.
Elsewhere in Shetland:
The far north west of Shetland Mainland is excellent for walking; Ronas Hill despite it's modest height, feels much higher on top, and it is worth heading west from the top to take a look at the crumbling Lang Ayre cliffs; judging by the trenches running parallel to the top, the whole lot is subsiding into the sea! Point of Fethaland lighthouse is a good walk, and Eshaness is worth a look (Dore Holm must be the best natural arch in Britain). Spectacular coastal scenery. There's a campsite with pods at Braewick, and the fish and chips at Frankie's in Brae are to die for.
Down south, don't miss St Ninian's Isle, connected to the mainland via a superb tombolo. Sumburgh Head lighthouse visitor centre is also worth a visit.
For food I strongly recommend spoiling yourself at the Scalloway Hotel;
