Customising Breadcrumb NavXT [closed]

For option a, see the Breadcrumb NavXT FAQ.

For option b, since there isn’t an all encompassing “current item breadcrumb template”, you have two options:

Since all the unlinked breadcrumb templates are used for the current item, just replace the %title% and %htitle% tags with 'You are here'.
Write a filter for the bcn_breadcrumb_title hook, check for the current item and programatically change it to 'You are here'.
