Recently I was in a 737-700 during my trip. I noticed that the
landing speed was quite high. Anyone know what the normal landing
speed is for this aircraft?

110 - 150 knots air speed, depending on weight an flap setting.
The ground speed may seem high with no wind.

Also, I noticed that there was another way to slow down the aircraft
after touching down. Was it reverse thrust of the engines? I am
confused because reverse thrust would cause engine overheating (that
is, there would be no air flowing through the engine but pushed out by
the reverse pitch of the blades)

The CFM56 core air flow is not affected during fan air flow deflection
and reversal. Older models with JT8 engines reversed all the air using
bucket deflectors, without overheating. Compressor and fan blade pitch
can't be adjusted on jet engines, only stator blade angle of attack.
