If it could be bought for the right money it would meet your needs perfectly for years. Rather than chopping and changing.
If you're planning on spending a lot of time with the big boys, you'll probably be better off going for a bigger boat altogether (>5m). Depends what you're planning on using it for. Sub 5m Ribs are great for trailing, launching, petrol bills, etc., but it's when you go playing in the rough stuff that they tend to show their weaknesses. As Alice says, if I were you, I wouldn't want to be considering upgrading again in a few months' time.
As for hp, I like to go for the most I can afford (and the boat can handle). You don't have to use it all, but when you need more, it's nice if it's there.
