Like many above I've never used anything other than regular 2 bolt SPD as clipless pedals.
What kind of pedals? I'd go for Shimano M520 or M540. If the over-used term "bomb proof" can be applied to any cycling components, then it's these. M540s are a little more expensive a bit lighter and generally a bit better, supposedly the bearings are better but I never noticed any difference. Key to me is the M540s look a bit nicer, they're less stubby looking. These things are important
Shoes are very much up to you. I wear multi-sport shoes with laces that look just like trainers off the bike, but I don't think that's what you're after. I don't have any issues with "slipperiness" and I'm also large and clumsy.
