1) I'd say barely. It is useful since underlying platform is a lot similar to Unix and it gives you better understanding of how things work under the hood but -as an iOS programmer- you do not have direct access nor control of the OS, and all tasks *MUST* be performed with Cocoa/CocoaTouch framework tools.
Don't expect to be using SSH, grep, netstat, nfs, df, bash buit-ins, etc in any of your programs.
2) Again, you won't be dealing with syscalls, forking, IRQs, etc. It's not necessary at all; however it's a good plus. Even if you're into multi-threaded programming, Cocoa handles everything without (much) hassle.
3) I'm not a Linux programmer myself but if you are already proficient with Objective-C you're most certainly a capable C programmer so you'd at least be able to "talk" in same language. Now you'd only need to learn the internals of Linux and get familiar with its code.
