I just added two pages to the wiki above.
The first is an image that shows how much it costs to raise your base attributes. (I also showed what it would cost if you could raise them to level 7.)
The second page is a link to a spreadsheet that has tabs for all the different manuscripts, how many you have to combine, and what they do. It's broken into Machines and Rites, Praetor Manuscripts, and Legion Manuscripts. I also included the table for increasing attributes.
Let me know if you can think of anything else that is needed.
