I have changed my sprockets and chain. Here is what I have used:
32mm socket for the front sprocket nut
27mm socket for the wheel axle nut
24mm spanner for the wheel axle bolt
New 12mm nut and washer from here:
THE KIT CONTAINS:
90179-18006 UPGRADED NUT
90215-21290 WASHER

http://www.diy.com/departments/ffa-concept-steel-round-tube-w30mm-l1m/254227_BQ.prdThe best £9 I've ever spend. Removing the old sprocket nut was very easy with it.
Here it is in action:
Draper 30-210nm torque wrench - have used it to do the new nut to 90nm.
Note there are two types of chains: soft-head pins which are hollow and much more easier to rivet and the good rivet tools for that are about £30, and hard-head pins need expensive Whale tool.
For example I am looking for Tsubaki chains because the price matches the cheapest low strength chains and the quality and strength matches expensive ones like D.I.D.
I also found Tsubaki chain installation videos very helpful.

Hence I decided to go for Alpha XRG because I am lazy and want to do the things easier.
Bought Warrior rivet tool:
http://www.demon-tweeks.co.uk/motorcycle/chain-tools/warrior-heavy-duty-chain-riveting-viceInitially I was thinking to go 14/49. The 110 chain was too tight with 49. Hence I have installed 14 front 48 rear.
When you untighten the front sprocket you will need somebody on the rear brake or a big hammer with a wooden handle and a T-shirt. Make sure the handle rests well on both swimgarm legs and move the wheel forward to press the hammer handle agains the swingarm below the handle. Using right foot keep the wheel pressed against the hammer handle. Then use the breaker bar to untighten the front sprocket. With your left hand you press on the socket against the nut and also with the left hand you push down and backwards, so that you DO NOT overturn the whole bike when you pull up and forward with your right hand the breaker bar to untighten the nut. Do not forget to straighten the old washer on the front sprocket first like me.
For the old chain I have used a dremmel tool to grind off the pin heads first and than RYDE HEAVY DUTY MOTORCYCLE CHAIN BREAKER to brake the chain:

Than used the warrior tool to rivet the new chain:
