That is what you need but it will connect from a PSU molex connector, not the motherboard header. You can still use that for one of you fans though.
You don't need that, but it will work just the same (Only, that one is mighty ugly).
You can connect two fans to one port using a Y-Splitter cable. One port will usually have enough juice for 2 fans, can't say as I'd recommend more than that.
What you have there is a Molex version, which means it will connect to the Molex cable from your power supply, running the fans at full speed 24/7 (Unless you use a 7v adapter) and giving you absolutely no control over them. Which completely negates the advantages of 4-pin PWM fans right?
A 4-Pin splitter may set you back a few more pounds (as do PWM case fans in general), go with a nicer braided one for aesthetics sakes.
One word of note is probably the obvious, if you or your motherboard adjusts the fan speed for that particular port, you will be doing the same to both fans. There's no way for the mobo to tell or send a signal to each fan, it simply treats it as one.
