To add to Rynn's excellent a response I would suggest having a solid idea of the environment you want your pantropic humans to live in and starting with less 'difficult' environments first or primarily.
Engineering humans to live in Earth's oceans or to be immune (or at least resistant) to the negative health effects of free fall is likely to be easier to describe convincingly than humans who are engineered to live in vacuum or on the surface of Venus. This is particularly true if you are in a fairly near future setting. The further into the future you go, the more latitude you can gain in this area, although there are still limits.
Hope this helps,
Todd
