To upgrade a Suburban to 8-speed, you'll need (at least) a rear hub and cassette. That's if you know how to build a wheel. I can't find any prebuilt wheels built on a cassette hub, so this may be a job for a good bike shop. Also, the rear triangle will need to be spread to fit the wider 8-speed wheel. That's definitely a job for a good bike shop. Whether the existing derailleur will throw the chain across all 8 cogs, well... I don't know. It might.
