You'll want to implement process monitoring using a tool such as monit, god, or bluepill among others.

Yes. conf.d files are included in Apache's configuration with a line like:

Include conf.d/*.conf

so changes are only noticed when the main configuration is reloaded. Note you can also use the 'graceful' restart (/etc/init.d/httpd graceful on some, apachectl graceful on others) to reload the configuration without dropping existing connections.

Your symlinks are there, but they're not what you want. If you notice, yours are all prefixed with 'K' for kill. They should be 'S' for start.

Fix this with chkconfig beanstalkd on and verify it with chkconfig --list | grep beanstalkd.
