Holy thread-resurrection, Batman. This is what I get for not visiting here very often.
Regarding your height and the bike - it depends on how you're built. If you've got long legs, you'll probably find the bike quite cramped. I'm 5'9", with 32.5" inseam, so I'm quite comfortable 99% of the time. On long hauls I do get a little stiff in the leg, but... it's a sport bike.
You're extra inch or 3 will probably make the seating position feel a little less aggressive. I find that I'm a bit over the tank to get to the bars, but it's nothing terrible. That having been said, the riding position is very aggressive - perfect for carving out the twisties here in AZ.
Also, the bike is quite narrow. A lot narrower than other 600s I've ridden. Great for me, but some folks may find that to be an issue.
Heat. The heat from the exhaust is actually not much of an issue. It's the heat from the engine that'll fry your thighs. Literally. (I've had burns.)The bike gets quite warm (read: very hot) when you're in stop and go traffic but is absolutely not a problem if you keep your speed up. So, if you're planning on using it as a commuter, you may consider the CBR.
Reliability. I haven't had any problems with my bike. Naturally, if you go to the 'tona
forum, you will see threads where people have had issues. The majority of folks, though, don't seem to have any trouble. Finky is right, though: parts are expensive and can be difficult to find.
BikeBandit will be your friend if you buy a 'tona.
Hmmm... trying to think if there are other issues that you might want to consider before getting a Daytona. I didn't notice where you're from, but if you're in a wet region, you'll want to know that the stock tires (Pirelli Diablo Corsa IIs). Ummm... that's all I can think of.
All that having been said - the 07 CBR looks like a solid bike, too. I was at a local dealership the other day and got to admiring the bike. I got offered a test ride, but was a good girl and refused. I'm certain that, had I taken it, I would have had a new bike in my stable. It's a beautiful machine that seems really well designed. Don't think it's better than the 'tona, but it's right up there.
Hopefully this doesn't come too late to influence your decision. If ya have other questions, feel free to give holla'. If ya PM me, I'll get an email and know to come visit these here parts.
