Long sleeves. Actually all long - a proper XL (not only for someone fatter, but also actually bigger and taller).
As for the chest size it depends. I think I'm somewhere around 42-43". It's my belly's size which changes depending on how much I cycle and how long I give up smoking for at the time.
When I'm in the drops powering up my closest french alp, the sleeve length is great, doing a bit of hoovering around the house I have Rapha sleeve turnups, result of big belly narrow shoulders :[
