Do I need a samba share setup?
Do I have to manually add the hostnames to the Linux slave files?
How could I get the two DNS's to interact with each other so the NT machine updates the Linux box?
Does rndc have to be running to allow named to run properly?
What kind of security issues do I need to look at?
Thanks

No.

No. You can use standard zone transfers to copy the information to the secondary name server.

This is automatic if using zone transfers, as mentioned above. It is all in the configuration of the secondary, if you go with zone transfers.
One warning with using zone transfers. If your secondary uses zone transfers, and the primary server goes down for an extended period of time, the zones might expire and the secondary will not have a source. Best practice dictates the secondary has it's own records. This is where you might want to consider some sort of file transfer from the NT (perhaps SAMBA might work for you here...).

No. This is a "controlling" type of utility. It makes it easier to update and control the name server. It is a good thing.

All-purpose box security issues apply. This should be done prior to putting any services on it. Best practice security issues can be reviewed at many Linux sites. Search on "hardening" your linux server. SANS (sans.org) is a good place to look as well. I have no affiliation with SANS.
(I just use zone transfers. They're easier.)
Do I need a samba share with NetBIOS running on the Linux for a zone transfer to work?
Thanks
Now how do I get the info from dns1 to dns2, using zone transfers.
Set dns1 to be the master, and change the options for each domain to allow the dns2 ip address to do zone transfers.
On the linux dns2, for each domain name, create something like the following in the named.conf file:
zone "thedomain.com" {
type slave;
file "sz/thedomain.com";
masters { ip.address.of.master; };
};
Now, every time the domain information changes on dns1, dns1 will contact dns2 to tell it the information for that domain has changed. dns2 will then do a zone transfer from dns1 and update it's records.

Nope - the transfer is handled directly through standard tcp/ip ports.
