How can I mine by mining pool?

[myaltcoin]

I create worker, and I run command:
minerd -a X11 -o http://127.0.0.1:12333 -u username -p password -t 3 -q

This will be solo mining?

If I run command from my computer:
minerd -a X11 -o http://127.0.0.1:12333 -u username -p password -t 3 -q

but for mining pool， whether I need to use:
minerd --url=stratum+tcp://poolamigacoin.org:12333 --userpass=youramigacoinaddress:x

just change the miner this way on my computer?

also any hint for create my own mining pool? is that easy?

When you go to a mining pool they will give you the commands and links to software you need to mine at that pool.  You may want to adjust those commands to fine tune your performance but it should work with the basic command line they give you

thanks
is the command format similar to:
minerd --url=stratum+tcp://poolamigacoin.org:12333 --userpass=youramigacoinaddress:x
