Rear wheel movement!

Ive got some new superstar evo switch hubs with flow rims. All fine but just a little concerned that today i had to take the rear off as i had a puncture. After i refitted the wheel, for some reason the rotor wasn't in the center of the caliper anymore but closer to the side so had to re shim the caliper.
All was fine after that and i rode to work and back on it, But after reading cubecrazy's post on his collapsing superstar hub its got me a little concerned. Not sure why all of a sudden the wheel would be a mil or so out, Also when i was peddling hard standing up with the bike going side to side, i was doing a down stroke with my left peddle so had the bike banked to the right my tyre slightly rubbed the chainstay.
never had that before but then again it might be the first time i gave it some like that since having the new wheels. If i push on the rim though from the side it will move about 5mm with force. Is this about right?
Just thought id ask the question after seeing cubes post as id sooner get the wheels checked by an lbs before something fails, Or am i being too cautious :?

The second thin gsounds wierd...maybe worth giving it a good look over or popping in to the LBS (but you won't be popular with a superstar wheel) just for piece of mind

Adjustment of what ?
Cone and cup are obvious with locknuts and my Fulcrums with cartridge bearings have a small collar to preload the bearings. Every now and then it needs a tweak. Same symptom - little bit of side to side movement.
Bear in mind that 5mm at the rim is probably only half a mm at the hub.

You might be right with the drop outs. I'm thinking the wheel might not of been in the drop outs properly the first time as I made sure the wheel was properly in this time.
Might just pop into an lbs tomoz if I get time.
Oh right. I'm not up on how all the bearing thing works, I've got some researching to do I think
The 5mm play in the rim is just me pushing it with force with my thumb whilst gripping the seat stay with my hand if you know what I mean. The hub ain't moving so its just the play in the spokes. But is there meant to be that much play or do the spokes need tightening?
Different superstar hubs, I have Superlegera and other than massive bearing failure there would be no way for mine to have the problem CC had.
Yours could be simple adjustment (cone spanner or allen key) or bearing failure, or a number of less likley issues, I'd check the bearing preload is right first!
