What problem are you trying to solve?  There's probably a better way 
to do it.

I can think of at least a few reasons that you should reconsider your
approach:

- - You want to connect to your home computer from untrusted machines.  
That means any trojans on those machines which happen to be capturing
passwords will own your home network.  It's foolish to trust public
Windows machines.  If you must connect to your home network from
outside, do it from a secure, trusted, single-user host, and tunnel 
all traffic (in which case the next caveat won't apply).

- - There's a good chance it won't work, because many ISPs block 137:139 
on consumer dialups.  I don't know of any that block 22 yet, though, 
which makes ssh (or an ssh tunnel) a good bet.

- - You want to transfer files over what will presumably be a relatively
slow link.  Remember that even if you have a high-bandwidth connection
at home, it's likely that it's asymmetrical, meaning your upload
speeds will be anemic.  If you're mounting entire Windows shares, 
expect to be disappointed under these circumstances.

- - You'll need some way to find your (presumably dynamic) IP address 
from outside.  A Linux gateway can do this by emailing its IP address 
to you at some predetermined interval (this is what I do), but it's 
still a bit of a hassle. 

If you just need access to a few files from elsewhere, consider 
copying them up to an external source (like perhaps your webspace at 
your ISP, if you have it) and access it that way.

Just my thoughts.
