Your's is almost exactly the build I'm going for, and I'm very happy as I wander along the path at level 46 now. I understand you to be asking more about sequence than recommended talents.
Here's MY strategy for sequence.
After taking Nature's Grasp and 1/5 Furor very early before I really knew what I was doing my strategy has been to go straight down feral to get HoTW, LoTP and iLoTP ASAFP. Now I'm filling out feral to hit the investment required to get my Mangle on. I don't know if I'd grab them right away again, but I'm happy to have them. NG can be a lifesaver in cat form when you don't have a bash to give yourself time to self-heal and the occasional but unreliable instant rage/energy of Furor is nice to have too...I find ways to take advantage of it about half the times it comes along.
I plan on stocking up on resto talents as soon as I get mangle. Others advise spreading the wealth sooner than that.
If you're focused on a "cat build" like you say, you'll probably want to get to mangle ASAP like me. As part of that you might wanna take 3/3 Primal Tenacity instead of 3/3 Thick Hide. I have neither so far. Perhaps I dislike getting stunned/feared more than most though...I friggin' hate it. In general, I've seen more recommendations against Thick Hide than for it. In fact, Thick Hide isn't in my planned build even though I like tanking almost as much as making things bleed and die.
I've heard others say that 5/5 Furor is a "must have" and you should get there as soon as possible, mostly for PvP but some value in PvE too. To me the instant rage/energy is nice but not required. But "others" are usually smarter than me so you might want to take that early instead of waiting as I plan to.
