Shadecloth covers assist in growing. Keep up the water.

Lettuce won't germinate if the soil temperature is too high, but if you can start them somewhere shady they might do ok.

Planning on planting tomato & lettuce together. Is this a good idea? Any advice would be appreciated.

Plant the lettuce on the northern side of the tomatoes or plant far enough away so that the tall tomatoes plants don't shade the lettuce. Lettuce need sunlight to fully grow.

Yes you can, but depending on how hot it gets where you are, you should choose a heat-tolerant variety or it will bolt too quickly. I recommend the red varieties of summer crisp Batavian lettuce. You should be able to get them at Swallowtail Gardens online if they haven't sold out for the season.

I live on east coast and wondered whether it is a good idea to plant lettuce seeds and what type for summer 2020/2021?

The open leaf varieties. Cos, butter crunch, oak leaf etc. Lettuce seedlings take a lot of care to grow. Seeds need to to be very close to the surface to germinate, only a couple of mm of fine potting mix or seed raising mixture to cover them. Water with a sprayer or mister not with a hose. Water 2-3 times a day, keep the soil moist. Will need to grow them for 3-4 weeks before transplanting them.
