Forget about max HR, it's an unimportant number. Look at the top of this forum and you will find a sticky telling you how to test for your lactate threshold HR. An alternative, simpler method is to go as hard as you can for 20 minutes (after a decent warm-up) and take the average HR for that twenty minutes.
Then look in Friel's bible. You'll find that there is a table which tells you how to set your HR zones based on that number. Most of your training will be in zones 1 and 2, with maybe 15% - 20% in zones 4 and 5. These proportions will change during the year, depending on whether you are in base training, or build, or racing frequently, and so on.
Keep reading. You'll figure it out. Absorb what Friel says about recovery, young riders -nearly all riders, actually - don't give themselves enough time to recover between hard sessions.
