2000 Toyota Corolla Rear strut replacement and alignment

I already replaced my front struts and then went to get a front wheel alignment. Now i was going to replace the rear struts once i had enough money to replace them, but found out I may need another alignment if i do. Is this true? Some say i do, some say i don't. Not sure what to believe. Also should i replace the sway bar links while i'm at it since there attached to the strut?

Thanks
