When wort is boiled, all the dissolved oxygen in the water is driven off. The wort is hot packed by racking and has no oxygen added at this stage. When you pour the wort into your fermenter, you need lots of splashing to reoxygentate your brew. Oxygen is very important for 6 hours at the very start of fermentation for yeast health. Do not try to oxygenate now. You will do more harm. Oxygen is the enemy of finished beer.
Different yeasts produce different amounts of krausen or foam. The presence of foam probably means all is fine with your brew.
Next time you want to add some more hops, don't just boil in plain water, add some of your wort to the saucepan and boil in that.
Don't try and seal your lid too tightly, or you will have big problems getting it back off again.
The wort kits make a great beer. I am sure it will be fine. India pale ale is full of flavour. One aspect of beer brewing is different styles and how they originated. India pale ale has its roots in England for shipping to the colonies. It has a higher alcohol content and more hops to help preserve it for the long voyage. It has nothing to do with American Indians, which is a common misconception.
