when you have driven the car around for a while, get out and feel if your wheels are warm around the centre/hub. When i hear you saying that it feels a little heavier from standstill it makes me think your brakes are sticking. I had this once, could clearly feel the rims/wheels being warm and this should never be the case when all is good.
Tyres wearing on the inside is normal when riding a bit of negative camber and toe-out. you can solve this/counter this a bit by doing a little(!) toe-in, makes a more stable straight-line drive too.
