It's 12 hours after your post, so you almost certainly won't read this, but you describe two serious hardware failures within the first nine months of ownership. That sucks, but Apple would absolutely have fixed both problems quickly and without charge if you had given them the chance. And if you're right about an overheating problem, they'd have fixed that too. Use your standard warranty! I also recommend buying AppleCare. It's not a trick like most extended warranties, and it's fairly priced.
