Its personal preference really.. I guess until you have tried it a few different ways and with varying amounts of priming sugar etc. you wont know what your preferences are...
I find with ales 5-7 days at 18-20C is fine, as long as the beer gets another 2 weeks (at least) in a cooler spot (so that CO2 gets into the beer itself) then its spot on...
I've just moved the IPA I bottled on Monday to the understairs cupboard, whre its nice and dark and stays at 13-15C all year round

This brew should then be ready come Mayday weekend, although as its a hoppy one will continue to develop with time!
But I like this style with fresh hoppyness, like the American IPA's...

Slainte!
