I speak hardly any French either old chap, but it has never proved to be much of a barrier.
The best way to see Paris is on one of the excellent open top busses, as long as it is not raining.
The Louvre i guess is a bit of a must to visit and the Eiffel Tower if you have a head for heights. The highlight of my visit was going to here Daniel Roth play the organ at St Sulpice. If you like organ music, it will blow your brains.
Hotel and food prices are as not as bad as London, but the fall in the Euro could have changed that over the last year. I used to stay in a Hotel near the main train station and the prices were reasonable. The closer you get to the centre of the City, the more expensive it gets i would imagine.
If you are going to use the new high speed rail link, Paris is only a short hop away.
