First off, yes, all the templates are NN compatible.The difference between NN and IE is basically a fussiness about code. IE will overlook errors and try to 'guess' what you were getting at, NN will not. How difficult it will be to make already created pages cmpatible depends on the reason why they are not working in NN in the first place, it may be very simple or a pretty big job.
It is not however as simple as making a copy and then retrospectively changing the compatibility. In fact all the compatibility settings do is prevent you adding components and effects work in IE but not in NN - such as some options related to table borders and backgrounds and the DHTML effects. It will neither prevent you from entering bad code in the first place nor fix it if you change the compatibility later. It is an aid, not a complete solution.
Do you have a URL? Having a look at the pages and seeing just what the problem is in NN would enable us to give you a better idea about what will be involved in fixing it.
Having two sites, one for each browser, may seem an attractive solution but it is not. You would then have two sites to update and maintain and keeping them coordinated would be a nightmare. And anyway, if you have a site that works perfectly in NN you can be pretty sure that it will be absolutely fine in IE, negating the need for two sites.
