Ok let me put in some perspective from a person who has only lived in melbourne for 1.5 years.
As lame as the touristy things seem to locals, you gotta do them. Look like you have covered the main ones. I enjoyed the aquarium.
One thing you might want to do is go to Eureka Skydeck. A room hangs out over the road from really high up lol. This place is in Southbank not to far from the crown.
Since you will be at the crown (near queens bridge), tram 55 will take you up to Queen Victoria Market and if you stay on long enough it will also take you to the Melbourne Zoo. Head north on the tram not south haha.
Italian Food:
--------------
- Lygon Street is good for a lot of the traditional italian food. I like Papa Ginos. If you go to Lygon street make sure you eat Gellato. The best one is on the right side of the road (if looking up into lygon from city end, i think there is an indian resturant near there too - same side at least). Pestatio is my favourite haha.
- Risotto. Best place for this is Tutto Bene in Southbank
http://www.tuttobene.com.au
- Modern Italian (expenisve smallish dishes) - Scusami in Southbank
http://www.scusami.com.au or IL Bacaro in CBD
http://www.ilbacaro.com.au
Check out my private food album (i take photos so when I return to resturants I know what to order as menus usually have no images). If direct link doesn't work for you, PM me and i'll unlock it for you.

Some eating places in CBD:
- Hardwarte Lane (Various foods)
- China Town (Rainboy Palace - i think its the name, has good YUMCHA if you like that sorta thing)
- Swanston Street (mainly asian food, low end dine in stuff)
- Longsdale Street (near Queen Victoria Building) has Greek food. never had it personally.
Night Life
----------
This one is easy walk into the CBD. wait for a herd of hot girls and follow them. They will lead you to some clubs haha. I did this in my frist week here ended up somwhere in a side alley off Russel street near Penguin Statues. The venue wasn't that great but the girls were good. But yer myself I dont go out much to clubs anymore I feel too old amoungst the younglings haha. I still to the pubs.
Shopping:
-----------
Chadstone hands down. INTERESTING FACT I LEARNED FROM A LOCAL: If you looked at satellite images of chadston from about 2008, it looked more like a penis. So they modified the car park to blend it in. but if you look you can kind of still see it.
Finally check out those internet event pages to see if there is any events on during the week you are here.
