Aerating a lawn before seeding it or adding new grass seed is a smart decision. By loosening up compact soil and allowing it to take in more air and water, your seeds will have an easier time establishing roots and growing. Aerating beforehand also means your seeds will have better contact with the soil, so more of your seeds have a chance to germinate. If you do plan to aerate your lawn before seeding, aerate about two days before you plan to start seeding.

Provided you're using an appropriate starter fertilizer for grass seed, you can put down seeds and fertilizer at the same time. However, putting them down separately, one after the other, on the same day will help to avoid over- or under-applying the lawn food. Avoid using a fertilizer with weed control elements, as these will likely keep the grass seeds from starting.  

You can, like you can put too little down. Sowing too much grass seed can create competition between the seeds for resources (light, water, nutrients) and the seedlings could struggle to grow. When you sow too few, your lawn will come in thin. Your seed product has a recommended seeding rate, so use that as your guide.

Yes, after the lawn is overseeded post-aeration, most of the seed germinates in the aeration holes. This leaves the soil undisturbed while lush and healthy grass will grow in the holes' place. The point of this is to create extra turf density in areas that really need it, such as a large patch of dead grass where a shed used to be.
