I found some answers to my above questions so please disregard the (original)
message above. The only questions I have now are:

1. How many should I set for 'max external depth'? By default, there's no
value inserted, what does this mean? Is this the same as '0' value?
2. How many should I set for 'max number of connections'? By default, there's
no value inserted, what does this mean? Is this the same as '0' value? I don't
mind HTTrack monopolizing MY bandwidth (but I don't exactly want to abuse the
bandwidth of the website that I'm mirroring).

3. If there's no value inserted for 'max number of links', does this mean I'm
capturing ALL the links of the site I'm mirroring? Again, no value by default
and is this the same as '0'?
Thanks in advance!
