Most important thing is your feel for your own reworkstation. If you can, get a little practise how high you have to go on dead boards but 250°C sounds too low. 250°C means your hotairgun is 250°C but the stuff you try too reflow is lower. But it really depends on your station.

Use a small nozzle and watch your airflow, to much and more stuff goes flying.
 
What you will need
 
good tweezers that really grip those small components
 
the reworkstation
 
some noclean flux can be helpful, but for those 2 parts you can manage without.
 
retin the solderpads and make them really shiny but do not leave to much solder on there
 
add some flux (if you want) makes the solder flow better
 
grap your tweezers and and position your filter and position it but do not let go with your tweezer
 
heat up until you see the solder melt (this process should not take longer than 10-45 seconds) if it takes longer you are using to low of a temperature which also is harmfull for the logic board
 
repeat that process for the capacitor
 
try not to use solder paste if you are new to this (you tend to bridge stuff and possible creating shorts)
