Is it correct to say that as the Earth (or any other planet I guess) gets closer to the Sun during parts of its yearly revolution, that (at incredibly small levels) gravity on Earth gets stronger (weaker?) ?
Not really. But you can say that the tides from the sun get very slightly stronger.

Surface gravity measured at any point on the Earth's surface with a gravimeter will vary slightly with time, due to tides and tidal effects.

See for instance

However, there should be no average change in the Earth's surface gravity due to the proximity of the sun.
