I don't know about "HD and Full HD", but there is a difference between 1080p and 1080i, but it only shows up when you are watching things shot in 1080p. Remember, the picture you view will only be as good as the weakest link. Meaning if it is shot at 720p then 1080 means nothing as the best you will ever get out of the image is 720p. If it is shot at 1080p and broadcasted at 720p, then the same thing. The best you will ever get is 720p. That is why right now 1080p means nothing to broadcast TV (as most broadcast signals are 720p and some are 1080i, but almost none are 1080p) and really for that matter means nothing until you step up to a BluRay player and have a BluRay disk in the player. At that point you have something that was shot in 1080p, playing in a player that can send a 1080p signal to the tv, which can in turn display at 1080p.
As for the refresh rates, same thing. Unless the program is being shot at frame rates that make 240 Hz advantageous, then you are still bottle necked by what ever the initial programming was shot in. TV's cannot make things look better, then can only take what they are given and reproduce it. If you have a very good signal to start out with, then a very good TV will make that look good. Otherwise, crap in is crap out. Just on a more expensive TV!

Everyone hooking up TV, Home Theatres and DVD players, should read this little article to "try" and understand what the electronics industry is doing...and learn, hopefully where it is going.

It is a good article and might help you solve some problems, or get your expectations in-line with reality...or blow the whistle on a salesman trying to sell you something you don't need, or won't be able to get.
One thing is for sure, and that is that the broadcast biz and electronics biz is moving at light speed on this, and if you bought stuff only 2 years ago, you are already holding stuff that won't take advantage of things being delivered today, and likely the same will be true in 2 more years. For example, the true hi def platform is set at 1080, which will soon be the new broadcast by nearly all stations that have enough cashflow to install it and begin broadcasting...so if you buy the cheaper 720 you will already have a "lesser quality" tv. Of course, how much definition can really benefit from...most people can't tell the difference now!
While that hasn't changed much, the digital switchover has really excellerated this change. Refresh rates, definition, and modular components are all changing much faster than even some of the industry is able to process it.
Therefore...watch out. You might be getting sold on stuff that is already being fazed out...or won't take advantage of things coming down the pipe in only a few months.
