The most important French you will need is "Deux grande bierres s'il vous plait"!
Good advice offered here, but personally I would suggest that you don't get too fixated on Mont Blanc as your objective, particularly by the Bosses ridge. It is really seriously high, and altitude normally tends to be associated with suffering and unpleasantness, rather than any sort of enjoyable route. On the other hand there are all sorts of Alpine routes that are lower down that can be worthwhile as routes, rather than just a named tick, this will give you the chance to get Alpine experience and find out what the big mountains are all about. Actually the Bosses ridge is not a wonderful route to eventually climb Mont Blanc by, there are much better routes when you have aquired enough experience to go for them. In any case, you should have lower level objectives in case the weather high up is too bad to go for the Blanc, lower level peaks can still be perfectly doable in that case.
Chamonix is not necessarily the best place to go, especially not for a first Alpine trip - it is crowded, busy and gets quite a lot of bad weather. Lots of threads about where is best to go for a first trip, worth searching for them.
Finally I wouldn't worry too much about not having a partner, rather advertise for one closer to the time. Obviously the more experience you have gained, e.g. Winter in Scotland, not that that is any way trivial in itself, by then, the better you will appear to potential partners.
