How much smaller will the file be?

Size reduction varies. PDFs with many color images see the biggest reduction. Text-only documents may not change much in size.

Will text still be readable?

Yes. Text clarity is maintained. Light colored text on dark backgrounds and vice versa remain readable in grayscale.

Can I convert back to color?

No. Grayscale conversion removes color information permanently. Keep your original file if you might need the color version.
