As for which bits I'm confident about...I'm not really sure! I guess sight-reading is one of those things I'm quite good at so it doesn't scare me. The viva could be quite bad if the questions I'm expecting don't come up, it really depends how the examiners are with you! Recital prep is going ok, could be better. I've been playing some of the pieces for ages now and I don't want them to sound like I'm bored with them, but I still need to work on them so it's a difficult compromise.
My son was most worried about the viva too, but on the day he really enjoyed it, because it was more of a conversation than a grilling. He found the examiners very nice; they started off with things you really ought to know and then went deeper gradually, so he never felt they were trying to catch him out, just gently probing his knowledge. It's fairly easy to turn the conversation to things you do know about, as many of the questions are fairly open. Provided you know your stuff, you'll be fine.
You're right that the pieces need to come over fresh, so once you've finished working on them try doing a third of them each day, so that there are three days between. If you do lots of exercises and other pieces it will keep up your sharpness and stamina. Obviously, you'll need to run through the whole thing with your accompanist a week or so beforehand to make sure the timing's OK, but don't do every piece every day or you may get stale.
Hope it goes really well!
