RMAN recovery question...

I'm new to RMAN and have a recovery question.  We're recovering
our test database to a point in time.  The database is around 60 gig.
When we start recovery, will RMAN re-create, restore and then 
recover all the database?  And this may be a stupid question,
but  if more-current files are there, is RMAN intelligent enough
to just restore the changed blocks?  It was a full on-line
backup.  And depending on the answer, should I delete all the old files

or can I just leave them as is?  What about channels, can I allocate
more channels for a faster recovery?

Here's my script which I'm planning on doing command line:

rman target /
connect catalog rman_xxx@rcat

(password)

run {
     set until time "to_date('19-JAN-2007 18:00:00','DD-MON-YYYY
HH24:MI:SS')";
     allocate channel ch1 type disk;
     restore controlfile ;
     alter database mount ;
     restore database ;
     recover database ;
     release channel ch1;
    }


Check to make sure temp tablespace is there

alter database open resetlogs;




Thanks so much-
