Very much with recommending Dave Dougdale and also add Phill Bloom. Some great stuff on both those sites.
I'm also much of a view that you can learn some worthwhile lessons from using cheap gear. You will ditch it very quickly but you will also learn a great deal and appreciate why the expensive gear is worth spending the money on, or not. You have to look at the cheap stuff as a write off though so you will spend more in the long run. (But you will spend it from a position of experience so you will better judge how far you want to go with your next purchase.)
You don't appreciate how good a Porsche is unless you have driven something else first.
The best way to establish what YOU want is to get on and shoot some (lots) of video. It will quickly become apparent what YOU need. If you shoot outdoor events in the sunshine, fast glass and lights wont be as important as an ND filter for example.
Get an average price tripod and a monopod and see how you get on. You don't want to spend £300 on a Gitzo Monopod if you never use the one you have or £600 an a Schatler tripod and head (which is still exceptionally good value) if you always use a monopod.
If you spend £130 on a tripod and £130 on a head you will be surprised how much use they still get even after you have upgraded (as you will if you carry on doing video) but they should be adequate not to annoy you in the first instance.
My first mic was £30 and the next 5x that (and that is still cheap) but I appreciate the difference. My current mic does what I want at the moment. In due course I have little doubt I will be spending £500+ on a mic but, by then, I will know why I am spending that amount. I could have saved myself £30 and bought my current mic first but then (perhaps) I would now be closer to the next upgrade.
Audio gear is hugely complex and also very subjective. I know people who swear by eBay lav mics because the look at them as a consumable. Others would shudder at the thought. Audio is helped considerably by proximity which is where even a cheap lav scores - because it is closer to the sound source than any other noises. Once you have got to that point it is then down to you how much the quality annoys you, or not, as to how much more you want to spend to improve upon it.
