Crankset/gearing question and opinions regarding drivetrain replacement

Hello everyone,

I have a '93 Mongoose Crossway 625, not a fancy bike by any means but one that I have enjoyed riding and wrenching on recently.

The bike currently has a 3x7 drivetrain with front sprocket in 28,38,48 tooth count and a 13-28t rear cassette. I have a set of Sram 3x9 X9 shifter set with X9 rear derailleur, Raceface crankset in 22,32,42 and an 11-32t rear cassette. These parts were previously installed on a 26 inch wheeled mountain bike I once had.

My question is, what do I lose or gain in gearing by installing these parts on the bike with 700c wheels? I mostly use the bike for recreational riding around the 'hood until I lose enough weight to ride my "nicer" bikes. Will I end up spinning the cranks and not going anywhere due to the smaller sprockets in the front?

Admin, if in the wrong forum I apologize, I wasn't sure where to post this question.
