a) Getting used to someone else's habits always is a little, I think, but when I moved out I was so sick of living at home that anything seemed better, and by the time the novelty wore off we were used to each other :)

b)When things were difficult, I handled it by going 'okay, WHY is he acting like this?' and by making sure I didn't hold a grudge. And getting things out in the open. Don't let little grievances fester. That's the most important thing. Have a little argument now when you can easily make it up, rather than letting them build to the point where you have a huge argument that you can't just pout for a bit over and then go ask for a cuddle afterwards.

Change is scary. But it's probably scary for him too, even if he won't admit it. You'll be fine, and you'll have fun :D

Ah, you think you're prepared for the smells. I smile at the innocence, but at the same time I grieve for the awakening you will have. Boys' bums, seriously. There's something abnormal going on up there.

I think Trojie has the best words of wisdom, actually. I'm not living with a boyfriend, just with a housemate who happens to be a man. Once a month we find me going absolutely mental at him over the slightest things. We've both found it helps to stop and think "hang on, why is she doing this?" When he realises I'm hormonal, he doesn't take it personally, and when I realise I'm hormonal, I immediately say as much, and apologise for not really being that in control of what an enormous bitch I'm being. Overall, it works pretty well, and you can see how it wouldn't if it were never commented on. So that's probably your best bit of advice to take on board - always consider the whys before you jump to being royally pissed off (and hope to Glod he does the same).

What shelving system have you decided on? Are you merging books or keeping them separate? Alphabetised? Dewey decimalised? And how many books - have you been sad enough to count?
