I don’t think a grad filter is going to sort out bright skies in daytime – it’s just too bright for them to make a difference! A polariser certainly makes a difference. I think I shot this one with a polariser:

But as above, you want to have a low ISO, and high shutter and/or f number. You don’t need a tripod for daytime photos in bright light, only once shutter speeds are low in low light/night or you’re using something like a 10-stop ND filter for long exposures.
Tripod-wise, this was my first tripod: http://www.amazon.co.uk/CamLink-Camlink-TP2500-Tripod/dp/B000TCSMUO/ref=sr_1_4?ie=UTF8&qid=1437090075&sr=8-4&keywords=camlink+tripod
Bought for about £35 at the time from Jessops. Had very few problems with it, although now use something a little more sophisticated (and smaller, and lighter), but at £10 on Amazon you’ll not go far wrong!
