Ferts: I agree with Lee; if you use the calculator you can specify your exact tank size, and will be directed exactly how much to dose (in grams). In the meantime (until you get a dosing scale), the calculator also allows you to see the result of dosing each fertilizer for a given amount of teaspoons. If you try this, you will see that dosing for the 40-60g tank is closer to mid point that EI recommends than the 60-80g (which would be on the high side). I would stick with the 40-60g chart for now.
CO2: For good growth, and to limit algae, many will recommend you reach a steady rate of 30+ppm of CO2 for the photo period. Counting bubbles is not enough. You need to attempt to measure your pH prior to starting CO2, and then increase the bubble rate until your CO2 drops by 1.0 - 1.2. Some people use a drop checker, and when it turns the correct color then you have reached a good level of CO2; but the pH method is a good way to start. It will take you some time to slowly adjust the bubble rate up until you reach the pH drop you want. And you have to be careful with your fish/shrimp; as you increase the bubble rate watch for signs of distress (as too much CO2 is toxic to them).
Lights: I agree with you approach to limit the light at the start, and increase it only after you are confident your tank is algae free. Too much intensity, or too much duration is a recipe for algae.
It is good you are planting heavy, and make sure your tank has good circulation. Root tabs may help as well.
