Just to clarify - one will see some variation in Western Rite Orthodox practice. To begin with, one is only likely to see the spoon with children and the infirm (as have been long standing Western practice.) All Western Rite Orthodox use leavened bread. In the AWRV it tends to be wafer shaped, from Charis breads in TN (who make leavened wafers just for AWRV parishes.) In ROCOR Western Rite one will see small round loaves marked with a cross like seen in some Anglican traditions, and pre-Schism (as prescribed by the Council of Braga or Braganza - one of the two, I'll have to look at my notes; requiring it to be round, leavened, whole, white fine wheat flour, and fresh.) One might receive in intinction in some places (of wafer or particle being dipped in the chalice), or receive the host or particle on the tongue and then the chalice, or even as one does in Byzantine St. James - receive the wafer or particle in the hand, then receive from the chalice (no problem, since the hands of an Orthodox Christian are anointed at chrismation!) Communion is received kneeling in some places, standing in others - nothing wildly different than Eastern brethren have in the totality of their own traditions - the only exception being far less use of the spoon (after the Ecumenical Council which has the canon that reads that 'instruments of silver or gold' are not to be used to commune the faithful.) At one time after the schism, some Westerners had adopted something along those lines - a sort of tube or pipe - now only a thing seen in books and museums. Otherwise, the only other thing I could add is that various Western Rite clergy have preferences about certain methods above - with varying degrees of insistence (very similar to Byzantine clergy.) The important point is that all is done reverently, for a very good reason - and within precedent and canonically for Church tradition.
The same goes for kneeling or crossing oneself - there is also some variation (the old Celtic/Sarum method is more like the Eastern, the same English tradition also has no kneeling genuflection, but slight and profound bows.) In which case, the old Byzantine proverb about not taking one's typikon with them when visiting another monastery applies - I've communed in both (including St. Peter's), and can agree that the priests are friendly and will instruct gently (or, all the priests I know personally.)
