I've never been to Winton so I'm probably not the best person to talk to about this, but I have been to quite a few Clipsal 500's in my time including this year.
One of the first things to do when you get to the track is to buy a program. They should be around $5-$10. It's disappointing that you are only going on Sunday and not all 3-4 days, but that's just how it is.
Will you have general admission tickets or numbered grandstand seats? If you have general admission (you can do this if you have grandstand as well) is to get there and in the track right as the gates open. What you should do then is, spend a couple of hours walking around the track and then figure out the best spot that you want to sit at for the day. If you have general admission, you'll be able to sit anywhere that isn't a major grandstand, so you can move around during the day.
One important thing to note is the pricing. At the track, most if not all of the food places will cost a lot. What I did this year, and is best on your pockets, is to buy some snacks from the local mall/supermarket and also make things like your own sandwiches (or whatever you preference, but bring both snacks and sandwiches). It costs you much, much less overall. If you want to try out the food there that's fine as well.
You don't need to worry about bringing ear muffs. At least, I don't think so. I don't know what support categories will be there. You definitely wont need them for the V8 Supercars.
And relating to the last one, time you walks around the track with the times that there are no racing on at all. Always watch the support category races. Sometimes they are just as good, if not better than the V8 Supercars races. The support categories are also very exciting.
If it's anything like the Clipsal 500 is, not too long after the Sunday events finish, the track should be open for you to walk over. If you can do it, walk a lap of the track. It gives you a really different perspective from what you see on TV and your seat. Just check though before you wander on to the track though, I can't guarantee anything. :P
And when you are wandering the around the track trying to find a place to sit if you do have general admission, make sure that you find out quickly where the nearest toilets are. Also try and sit near a big screen and near one of the speakers you know what is going on around the track.
Conor Daly has flipped at Monaco, Indianapolis, and now Abu Dhabi. He had a large crash during GP2 testing at the same corner that Rosberg and Karthikeyan had their large crash a couple of years ago. Both drivers are okay.

haha. It's really depends what you define as real racing though.
I'll be able to see Sam race live for round one, hopefully I'll be able to meet him (and maybe even talk LFS) if the Porsche's garages are in the same spot that they were last year.
Former (I say former, he hasn't done a race since Aug 2012) LFS driver Sam Power will be driving in the Australian Porsche Carrera Cup, replacing Nick Percat (who is moving to V8 Supercars) in 2014. Nice job!
