The number is the ISO or ASA (both are a standards organisation) rating of the film that states how quickly it reacts to light.
The higher the number the more sensitive it is. Each increment is twice as sensitive for example
200 reacts twice as quickly as 100 this means that you can use a shutter speed that is twice as quick in the same lighting conditions.
There is a trade off between slow and fast films where the grain of the film gets courser the higher the speed, although, with modern film technologies this is becoming much less of an issue.
In answer to your question
50 for very clear detail e.g. portraits etc
100 - 200 is great for out doors.
400 a decent brand makes for a good all round film, better in dimmer light, maybe sports events, fireworks maybe. depends on how long you want your exposure to be
800 + for very fast sporting activities for example.
I hope this answers your question.

you should try jessops they don't have a large range but you will beable to find a range of films also you should look at jacobs. If you don't mind buying online have a look at www.7dayshop.com they have a large range and they are cheap.

late addition here but, since you're on the web 7dayshop.com is definitely great for all things film and photographic. it's a lot cheaper than jessops but you do have to wait up to 7 days, hence the name. for value that's where i shop for film, ink cartridges and both printing and printer papers
but if you need it next day Calumet is great but not cheap. that's on calumetphoto.com
hope that helps

oh and if you call fujifilm's technical department you used to be able to get a free "technical data guide". this little book has loads of helpful info regarding their films and how they react to different light/dark conditions. it'll give you a guide which will generally apply to most film makes and i've found it quite useful.
best of luck
