Yes to both! As long as you have a real address (ie not 127.0.0.1) then you will 
be able to operate your mythbox without reference to any other network equipment 
- with the proviso that the address you choose is *defined on the box itself*.

You /could/ do a static allocation on your router but that would mean that you 
would need the router on all the time.

(I would point out here that if you are running mythfilldatabase to get your 
listings, you'll need a regular internet connection anyway, and by 'regular' I 
mean 24/7.)

The mysql thing is because you've already set your system up and mysql probably 
has references to 127.0.0.1 - and quite possibly some other random things, like 
the hostname, the fully-qualified-domain-name and other accidental stuff, 
possibly with strange password entries to boot.

You'll have to query your database and find out what values have been stored to 
allow you (I mean the mythtv programs) to access the database and where those 
values are stored in the filesystem: I'm talking about mysql.txt, config.xml and 
various apache config files if you intend to use mythweb.

That information is going to vary according to your distribution and the exact 
way you set your system up, so will be different for everybody, which is why I'm 
carefully not going into any extra detail here. There's plenty of info here and 
on the wiki to allow you to fix this.
