well, the minimum time for primary can be as low as 20min, but i do recommend 60min. The washes, I do 3 times 20min in a 30-50ml for a minigel, but you can do shorter times, depends on your antibody. Nice western is a balance between high signal and low background, so if you get no background at all, you can easily shorten your incubation times, whereas higher background, you can either do longer washes, higher salt/tween/milk, or you can lower your concentration of primary...
