1. Yes, there are kits for high beams.
2. Never heard of H1R1, might be just H1.
3. $225 for H1 PHILIPS 6000k delivered, i do not recommend anything over 6000k for highbeam as the LUMEN rating is lower as you go higher in KELVIN rating.
Meaning the the higher the KELVIN rating, the brightness starts to drop.
EG: 6000k= 3100 LUMEN
8000k= 2900 LUMEN (this is still approx 3 times brighter than halogens)
