Power steering pump replace lexus is200 99-05

[Lzt002]

I need to replace my power steering pump because its leaking. I've changed basic things before like brakes etc but nothing involving the belts so bit anxious. To remove the power steering pump is it just a matter of undoing the slider bolt with the orange arrow to remove the belt then just undoing hose and bolts and replacing power steering pump then retighten belt with the same bolt? 

 

Any help appreciated just want to know what I'm getting myself into because I'm still learning about cars and not a mechanic. Thanks.
