Can I use these two together?

Yes. Paint with the Gloss White first, let it cure, then seal with the Rust-Oleum matte clear. The clear coat will knock down the gloss, so use a gloss clear if you want to keep the shine.

The Gloss White, at 12 minutes to the touch versus 20 minutes for the Rust-Oleum. Full cure takes longer for both.

Which covers more area?

Rust-Oleum states 12 sq ft per can. The Gloss White gives no figure, only that its high solids allow maximum coverage, so treat it as comparable until you test.

Is the Rust-Oleum a paint or a topcoat?

It is a clear matte topcoat in this listing. It protects a finish but adds no color.

Which is better outdoors?

Both are rated for interior and exterior use. The clear matte topcoat is the better choice for protecting an existing exterior finish; the white is for repainting.

Is the Gloss White worth the price?

At $159 for six cans at Distritech as of November 3, that is about $26.50 per can, which is high for a color coat. Check the Rust-Oleum price and other white spray paints before buying.
