I can't imagine there are 4 to 5 rows of buffs setup under the toons action bar. Maybe 2 actual rows. But you are right, there are lots and lots of "buffs" to get if you are going to be competitive. First off you should get buffed by the Entertainers on your server. Typically found in the Mos Eisley cantina, but sometimes other places too. They can buff your armor protection, critical hit chance, glancing blow, health, luck, etc. Make sure you tip them something. Its worth every credit. Secondly, look for a medic giving buffs. On the Chilastra server there is always a good Medic in the Eisley cantina along with the Entertainers. Between getting those 2 professions to buff you, you will add any stims, toolbar buffs, etc of your own. You will have collected these as loot from combat, or a few as a quest reward. Your profession and clothing/armor you are wearing can also give you some buffs. But as for 4 to 5 rows of buffs, i've never seen it. Hope it helps, and have fun!
