Ehh, I wouldn't get the kit. A warming filter is pointless. You have white balance control on your camera already. The UV is basically just a protective filter. The DSLR's have UV filters built in to them. The circular polarizer is about the only one worth getting. Even then you don't want to go cheap on these things for the reasons Csae mentioned above.
