If you don't have your kit already perhaps pop out and grab a small diary. I found it helpful to keep track of appointments and I used to write questions in there (often whilst waiting) otherwise I'd forget to ask. (Cheap as Chips was a good place to buy them)Try to have somebody with you as a second set of ears and for support.
I also bought one if those fold out files to keep all the volumes of information given to you. I put path reports, bills once paid etc in there. It really helped as I got brain fog really quickly due to the overwhelming stress of treatment and diagnosis and lack of sleep.
It is very likely they will recommend chemo due to size and nodes. Not definite of course. I found by researching scarf, hat wig options helped keep my head busy on more positive things and made me feel I had some control. Hope all goes well. Kath x
