I haven't had time to look into this. I imagine the first issue is a problem with Geiser. As for the second issue, note that the value of the 'org-babel-scheme-cmd variable is only used when external execution is requested (e.g., when session is set to "none"), otherwise session evaluation is used (likely using Geiser if Geiser is installed). Sorry I do not have more time to look into this at the moment. I you feel like looking to the code, a good starting place would be to run the command `edebug-eval-top-level-form' within the definition of `org-babel-execute:scheme' in ob-scheme.el, then running a code block and stepping through its evaluation.
