Thanks everyone 
I'm using CK and Experian to keep an eye on my scores and reports and have set up autopay on the former two cards - just waiting for the Amex to land in my mailbox before that too is put on autopay. Next steps for me would probably be to garden and wait for the BOA and Disco to unsecure themselves before requesting CLIs down the line...
I do have a question for the veterans here though. Would it be wise to gun for a 3x 61 day CLI with Amex in January? Bear in mind that I still wouldn't have FICOs at that point as my credit history would be 5 months old. I'm in this for the long run so if waiting is the best course of action I'll do that.
