Yep - that should do it - note the semicolon - very important ! ;D
You could also write a little script that did all the work for you in one step. All you'd have to do is put the one script on the player's Init field, something like this -
[this] exec "playerInit.sqs"
Then in playerInit.sqs you put things like addweapons, remove weapons, addactions etc. Easy as.
And if you're playing with respawn you just have the script wait until the player dies, then remove all the actions from his corpse, then after he's alive again add them all to his new incarnation.
Attached is an example that I use with most of my missions. Use, abuse or discard as you see fit.
