Save your money and wait 'til you can spend a little more; as Buckster indicated, 'a selt of filters' doesn't mean much any more (in B&W film days there were some "standard" sets). The most basic filters for landscape these days are the polarizing filter, and graduated neutral density filter. A decent polarizing filter is going to cost (new) in the neighbourhood of $70 on it's own, and a good one, well over a hundred. If you're buying screw-in filters make sure that you buy those with BRASS mounts and not aluminum. Remember too that even if you're using the cheapest kit lens, it still has probably millions of dollars of R&D behind it and a cheap filter can easily cause very noticable degreadation. This most often takes the form of softness, flaring and unusual colour casts.
