Hi Jonty, I hope the following helps to answer this:
Is peering going to give you benefits over transit. 1 major factor is that peering in most cases is free whereas transit is paid for so as part of the bigger picture it helps in reducing bandwidth costs. Of course, things like public peering exchange fees, port costs etc come into it but as part of the bigger picture it's there to reduce bandwidth costs, build a more resilient internet, open up relationships and create more direct paths. top 1000 destination subnets being routed to - This does really differ based on what traffic your network does. If you're a broadband provider you may find some of 'your' top destinations are youtube, iplayer etc. Whereas, if you're a data centre it may be more outbound to broadband providers and ISP's. You really do need something that will create this type of data output for you. We use Cisco's Netflow to pull out AS Stats but there's likely to be a lot of other alternatives out there.
