Will adding a second SPF record mess up my DNS, or will it be like adding an extra nameserver?

From RFC 4408:
I'm not entirely sure what you want to achieve by adding a second record, but if it is something like adding extra hosts/networks as valid/invalid senders, you can probably do everything you want to with just the one record - just add whatever you wanted to the end of the line.
