The suffix -lAş attaches to nouns or adjectives to mean "to become [noun/adjective]". Here, it attaches to the adjective güzel (beautiful) to create the verb güzelleşmek (to become beautiful). With the present continuous suffix, güzelleşiyor means "it is becoming beautiful" or "it gets more beautiful".

Is there another word in this sentence that uses the -lAş suffix?

Yes! The root of uzaklaştığın is the verb uzaklaşmak. It comes from the adjective uzak (far). By adding -laş, it creates the verb uzaklaşmak, meaning "to become distant" or "to distance oneself".

Why is it eşyalardan with the ablative ("from") ending?

The verb uzaklaşmak (to move away / to distance oneself) requires the ablative case (-dAn / -tAn) for the object you are moving away from. So, "distancing yourself from old belongings" requires the ablative case: eski eşyalardan uzaklaşmak.
