What's in a good rec letter?

Proper grammar is usually a good starting point...using has when it should be have is probably something you don't want people writing on a rec letter. Also, since when is this something you dictate? If people even use a rec letter, it is up to the person writing it to say what they feel is best. It's not a situation where you tell them the points they should be making and then they write it. To be honest, I never used a recommendation letter. I always arranged for people I knew would give me a good recommendation to be available to provide a recommendation. In interviews or conversations with potential employers, I showed my resume and if the opportunity was right, I explained that I had references available upon request. However, you are naive to think these banks aren't going to do their homework on you. It is a little tacky walking into an interview and shoving a letter that is largely verbose BS, not to mention the same for every candidate, in the face of every interviewer if that is your plan. Just a piece of advice, take it for what it is worth.
