If the present Earth holds a population that is far greater than it ever has been, and also the fact that our technology is getting bigger and bigger; Skyscrapers, oil rigs, piping houses, it all adds up. Would that added weight have any significant affect to the Earth's total weight, and if so would that then cause the Earth's gravitational pull to increase while also lowering the Sun's gravitational pull on the Earth due to it being a bigger mass?

The weight isn't added, it's redistributed.

Any increase in weight that a human or a human creation (like a skyscraper) undergoes is presently obtained from material that was already here on Earth. No additional weight is created. However, the Earth does gain several tens of thousands of tons of weight each year from space debris. It's such a negligible amount compared to the overall weight of the planet that its cumulative effect would take hundreds of thousands, perhaps even millions of years to be noticeable to humans.

It's not like we are creating something from nothing. The mass that makes up your body comes from minerals, water, etc. that was already in existence as a part of earth's total mass.

The weight from people on Earth is culled from material that already exists on Earth. New energy (mass) cannot be created or destroyed.

the phrase "you are what you eat" comes to mind, as we are made of the earth, we aren't adding weight to it, just moving it around a bit.
