Quick hid question

I know there's many posts about hid here, but I'm still confused of what I need if I want to get a hid headlight conversion done properly, I looked at ddm 's site, and there are many options to choose, harness, adapter, eliminator and brackets...
I know I want the hi and low beams keep functioning, as it'll be safer to drive in Idaho country road with hi beam... I also know 55 watt is probably too much, so 35 watt will be enough, and I think I'll go with 6000k

O yea, just a reminder, mines a 2000 es.
Please, I need advice on what I really need to make it work and last :)

Just get a hid kit 35w, 6k, your bulb size and done nothing else to it

Do I need to adjust it afterward?

Adjust what?

Like the angle so there's no glare that blinds the opposite traffic...

No but always double check and fix it if there is any

Okay, just ordered it, I'm excited for it, brightness and whiteness :)
