>What is a RJ45 economiser like this one What is a RJ45 economiser like this one
Ethernet uses 2 pair (4 wires). Standard ethernet cable has 4 pair which means that 2 pair are used, the other two are not. This device most likely will split the the cable into two 2-pair connections. You can do the same thing without this device by splitting the pairs when you're terminating the cable.
>Are there any pitfalls of using an ethernet cable extender much like you can with a phone cable extender?
Yes. Connectors are a weak point in the link. The fewer the connectors, the better. Length is a greater issue though. 100 meters is the max. If you go over that length, all bets are off.
>Is RJ45 just the connector type
Yes.
>Again, why so many types of ethernet cables. This 20m length is nearly £5 whilst this patch cable is only 50p whats the difference
Can't say, they're both the same link. :-o
I would get a spool of cat5e cable, some RJ-45 wallplates RJ-45 connectors and a crimping tool. Put in runs from your central point (where your internet connection is) to the different rooms. Then terminate the ends. If you want to get fancy, you can put in a patch panel at the central point.

each cable must come back to a central point where you ahve the hub or switch
you can put additional hubs in other rooms if you need them later - but you cant 'split' the cable.
one cable per PC - or per device (a hub will then share one cable amongst additional pCs)
rj45 is the connector on the end of CAT5 cable.
if you are having a proper electrician do this for you it would be nicer to have sockets in the wall - as it will look much neater.
