All of the above 
except blower should come with the cleaning kit.

You need to clean your lens or may be sensor so a cleaning kit should comes in handy

Extra memory card in case your primary one failed(if you shoot video class 10, if not class 4 is more than enough, if you do not want to transfer your pic every day then get the 32gb, get Sandisk, it'll never fail you)

Camera bag should come with your purchase unless you think you really don't like it then you can buy another one

cleaning kit no need to buy, ask the shop foc for u
usually comes with blower + microfibre cloth.

There's class 4, class 6(discontinued) and class 10, all different by the reading and writing speed. If you need to shoot video get the class 10, if not class 4 is sufficient.
If you like to transfer you pic out everyday, then a 8gb card is enough to take 400+ pic, if not then get the 32gb.

Filter, not necessary, you can always use the hood for lens protection. But in crowded area you never know what will happen and your lens might knock on something that scratches it. So let a 100 bucks filter got scratch is better than your 800-1k lens got scratch.

I would go for option (1), it would be easier for you to claim warranty etc since the shop is in your place. It is just RM50 differences, save you from traveling to KL. Your petrol, toll, parking etc.

Make survey at all shop 1st..then buy at shop dats offer best price..
