The first step in becoming an Olympic weightlifter is to not mix your pounds and kilos in the same paragraph without conversion. If you squat 135k and dead 180k, you should be able to clean and jerk 100 if your upper body is as strong. Start learning to front squat and keep your heels anchored. Heeled shoes are awesome, get a pair.
Until you work with a coach or someone with some experience, you're going to get only marginally better in regard to technique. A lot of the younger lifters I work with really benefit from hang cleans/hang snatches, it forces them to get under the bar without the benefit of their power. Learn to hang snatch and overhead squat.
Pendlay's program will be fine. Catalyst athletics will have a lot of really useful programs.
