Apache :: HTTPS - Generate Certificate And SSL Module

How to be able to fix my problem that is related to the https using apache2 (enabling https in apache2) at opensuse:

By the way, my opensuse version is:

openSUSE 12.1 (x86_64)
VERSION = 12.1
CODENAME = Asparagus

1) At the /etc/apache2/vhosts.d/vhost-ssl.conf, and if I do not have a name (as the server will be accessed using its IP address), can I place in the ServerName 192.168.0.5? Do I have to place it 192.168.0.5:443 or it is enough to be 192.168.0.5?

2) Is there a relation between the SSLCipherSuite values and the used method to generate the certificate?

3) I am afraid from the way that I am using to generate the certificate and the ssl module that is coming with apache2 at my machine which has opensuse. How can I select the right way?

Actually I used following commands to generate the .crt, .key and the .csr:

openssl genrsa -des3
openssl req -new -x509
openssl x509 -req

And that was from this link: [URL] .... But did not work with me !

Meanwhile I am placing:

SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL

4) Do I have to configure the virualhost? Do I have to create files under the directory /etc/apache2/vhosts.d? Because I will have one application to be browsed .. nothing more.
