Good to hear... But you need to post up some photos!!!
While I haven't got tints on my car, other guys at work who have IS250's have, and theirs also look a lot darker than legal under certain conditions, while actually being 100% legal. It'll depend a lot on the properties of the film used too.
As for the brake squeal, if it's under warranty, take it in! You'll get a complimentary courtesy car while yours is under the knife so there's no significant inconvenience to you..
