I've never asked questions because I feel I need to. If there isn't anything I want to know I just say I dont have any.
All the advice I've had from agencies and the like is that you should always have a question or two up your sleeve to ask.
Before turning up at an interview I always read up on the company, their history and their current product line, and then think of relevant questions. The aim is to present myself as someone who is interested in the company not just the job, and who is actually capable of independant, intelligent thinking.
Back to OP, questions about training and induction are always good, especially if its your first job within that specific area of business.
Off hand the two more generic ones I had written down for my last interview was:
"What induction / training opportunities are there" (that went down well)
"Where do you see the company going in the next 5 years" (Shows an interest in longevity of the role, that you're not just in it to get a couple of years experience under your belt)
Beyond that my questions were rather specific to the company and their product.
Oh, and always make sure you've got them written down (in a smart notebook or somesuch). a) it looks good, like you've actually put effort in; b) it ensures you don't forget anything.
