96 Nissan Sentra... Need head removal suggestions

I have a 96 Sentra with 120k miles on it. It has a 1.6 liter engine
and is automatic drive. I recently determined that I have a head
gasket leak (i.e., losing anitfreeze, consistent overheating, and
steam from the exhaust at startup). I have done head removal on
other cars over the years, but never on this car. For those of you
who have experience with this car, I would like to know:

1. Is there anything that I should be aware of or be careful of as I
do this job.

2. Are there any special tools that I will need other than wrenches,
sockets, etc??

3. What other procedure would be wise to do since I have the head off?
I should mention that I changed out the water pump because I thought
that it had something to do with the overheating. Would it be wise
to do a valve job?

4. Besides a head gasket, what other engine related items will I need
to complete the job.

I appreciate any thoughts you may have about this job.

Thanks, Al Kondo
