You asked for photos and here they are. Of all the chain and gear drives, brakes are caliper by the way, I don't like V or disc brakes.
Should have been so simple...

Thanks but I've bought the Crankset of the 48 teeth variety. Please have a look at the photos RAFN asked for I put on as many as I thought would be useful to get the advice I need.

Ok from the photos I think I would tentatively conclude the followings:
1. The BB is a traditional cup and cone one. If it needs to be replaced (because e.g. the cup is pitted, or a new chainset's requirement) then a C spanner and Sheldon's nut & bolt tool are needed. The use of the former to remove the adjustable cup is usually possible unless the cup is made of cheese, the use of the latter on the fixed cup could require some swearing...
2. From the photo that shows part of the chainrings I can't see any broken or obviously shark tooth shaped teeth, and the chainset does not look too bad to me to warrant immediate replacement. But if you have bought a replacement already I would say keep it just in case.
3. The photos aren't close up enough for me to be sure you have a Shimano splined freewheel. I wonder if you could check to see if it appears to have matching slots for this?
So perhaps the other question remains is whether the existing BB runs smoothly without play (when the chain is off the chainset) or not.

Well Cantilever brakes have been aroung for a very long time they look strong, they do the job and I have always found them reliable. They are simple sensible things and I feel very safe and confident with them. Also easy to clean and service.
V-Brakes look very fragile and I worry that they will come apart at the bracket, going down Wimbledon hill that could be fatal, they don't look reliable to me at all and I wouldn't feel safe with them.
As for the discs I think they are far too complicated and ridiculous overkill for a pushbike, frankly I don't see the point of them not only that but they are the kind of things I would be frightened to even touch to adjust. They are also ridiculously expensive and some are even hydraulic, that's lorry brakes FFS. They just seem like a way to add unnecessary expense to a bicycle and also a silly gimic to me. The more complicated you make things the more that can go wrong with them.
Well you did ask for my opinion, I don't expect people to like it.
Shame you have those thoughts as the V brake and the disc offer many advantages in terms of improved efficiency. The V brake is indeed simplicity and extremely easy to work with, whilst normal brakes will wear your rim down discs of course will not, embrace technology.
