Welcome!
All of the early milestones you mention are either at the high end of the chart or off of it, and it may be an early indicator of Giftedness.
Or it may not.
Having raised three gifted kids, all I can say unequivocally is that each developed and reached different milestones in their own unique way. My first cruised furniture at 6 months and was running by 9 months. My second refused to walk and speed-crawled until he was well past the milestone of when he should have walked. The last actually went through x-rays to make sure there was nothing developmentally preventing him from walking - which there wasn't physically but later proved to be one of the first markers for dysgraphia.
My advice is to record all the milestones - they'll ask about them in school when you're asking for gifted testing, and it's amazing how easily you forget which kid did what when. And my second piece of advice is to just enjoy your little one, try to keep them learning, playing and happy, and savor the days.
