I went ahead and took the plunge.
I've applied the Tooltips to a page, that already had Spry Validations on the Input elements of the page but the Tooltips dont show - I just get the standard Spry Validation errors still as far as the colour of the input elements are concerned but I get no error message now - neither the standard spry error or the new tooltip.
I see that the WA Code has been added to the page.
<link rel="stylesheet" type="text/css" href="webassist/validation_tooltips/validation_tooltips.css"/>
var WA_SpryValidationTooltip_ErrorTips = new WA_SpryValidationTooltip(15,5,20,"center","top-center",1,5,"#000","#000","#fff","#fff",80);
Am I missing something here? The webassist/validation_tooltips directory has been uploaded to the server.
