At that price you can try this tripod, but don't expect it to be stable.
By stable I mean: Do you really, really
trust your tripod to carry your latest and greatest photo-gear (new Olympus and all!)
Perhaps later on with a big lens
plus a flash
And tilt and swivel it with confidence, not expecting it to topple over
Well, just give it a try. But as soon as you suspect it to give up under the load, donate it to someone with a P&S...
As to macro: Well some people believe in extension tubes, some in close-up lenses.
My personal recomendation: the Canon 500D achromatic close-up lens because you don't have to dismount your lens (dust!) and they are simply the best quality. Be prepared to pay 100EUR (or equiv.) though and just make sure that the diameter fits your lens.

As to other accessories: I didn't believe in UV-filters until I got wet, wet, wet in New Zealand and had to clean/dry my front lense often. After that I went for this nice filter (buy Hoya HMC for good quality) purely for physical protection. A pol-filter is only for specialists - I use it in 5 out of 5000 pics...
