Understanding pedals

[jsmoke]

So you have flat pedals, the old pedals with clips and clipless.

Within clipless you have two or three different standards I think, SPD, Shimano and another.

And then you possibly have two bolt, three bolt of even four bolt cleats.

So for an entry level standard pedal/cleat set what am I looking for. Is it three bolt SPD pedals/cleats?

So are these SPD SL 3 bolt pedal/cleats?

If so it's not entirely obvious to me from the picture that a 3 bolt triangular cleat would clip into these.

Could you recommend a pair of shoes/cleats/pedals then.
