For my personal preference I would do it but at the end of the day if you cant afford it just yet then your alignment would be fine at least for a lil while anyway. You shouldn't have to change the tie rod threads which will change your Toe angle and you shouldn't have to touch the strut bolts(camber bolts) which would change your Camber. So your not directly affecting your alignment angles but removing one of the main components (LCA) and hitting the components to release the LCA could definitely knock the alignment off slightly definitely the Toe since that's the most sensitive. I would definitely get am alignment.
If you haven't done so yet, I recommend going to FireStone and paying a one time fee for $170.00 for lifelong free alignments whenever you need it. You'll get your money worth just after your 2nd alignment(most shops charge an average of $80 for each alignment you get
