No one really likes to say "yes you'll be fine", because we can't know, as we don't know you or your abilities. E.g. you say you can place gear, and maybe your gear is great, but maybe your gear is crap.
Disclaimer aside, Pinnacle Ridge is great fun and not too tricky; it's mostly just exposed - which is the joy of it! The crux, however, is a short bit of Diff climbing (maybe it can be avoided? Does anyone know? I don't remember). Go with someone of equal or more experience and take a 25m-35m rope and a very small rack (e.g. middle 6 nuts, slings and a couple of hexes or cams); if the exposure gets to you or your friend, you can then pitch. I think most fairly fit, outdoorsy and level headed people, given decent conditions, could happily work their way up the ridge unroped excepting the crux and possibly the awkward step down off the pinnacles.
I really don't think you'll need climbing shoes, but if you're less confident, wait for good conditions: dry rock and fingers that aren't going numb can be reassuring.
One good thing about Pinnacle Ridge is that it's not too tricky to work out the route (once you find it amongst the mass of scree and broken rock)! Apart from bad weather, I think one of the biggest dangers with scrambling is often that of getting off route and getting onto harder ground. It's important not to be too stubborn/foolhardy to retreat or avoid difficulties when necessary. Even if you're pitching, if you fall you might well do yourself some damage; it's really best to not fall - even if that means avoiding a bit of rock that "looks fun" and seems to *almost* match the guide description.
I think it's also a good idea to keep your group small and avoid taking multiple or much less-experienced people up until you're more confident. It's tempting to go up in a nice group, but if several people want a rope you're suddenly doing odd things like trying to throw a rope around a corner and hoping they can remember your instructions about tying in...
Good luck! I went up in December 2015 and thought it was fantastic. Afterward, you can walk over the tops down to Ambleside for a nice long day out.
