CFGrid - 1st maxlength for a cfgridcolumn/ 2nd - YES entered displayed as True?

I have an cfgridrow that should only allow 3 digits, is there a way to set the maxlength on a cfgridcolumn? If so, how is this done?

2nd:

I have a column for notes:

<CFGRIDCOLUMN NAME="TeamNotes" SELECT="YES" HEADER="Team Notes" TYPE="STRING_NOCASE">

if Yes is typed in and saved when the screen is refreshed it is displayed as TRUE (but in the database is saved as Yes) happens also with No (displayed as False) is there a way to make it displayed exactly what is in the database?
