I could never manage that long without a furry friend. how ever did you manage!
there are some great cages on zooplus if you want ideas. I suppose part of your decision should be what type of hamster! that of course will dictate wheel, cage etc.
as for the substrate most like care fresh or fitch

wheels you have the silent runner (which I have) trixie wheels in plastic or they do a wood version, the silent spinner. there are loads out there but do look at them all it took me over a month to decide on a wheel and two months on a cage.
my Penny is a plastic chewer which ment I had to put her in a tank type habitat.
there is a thread on the housing page called show us your cages if you want more ideas
