It doesn't apply to the rollover at all, but just in case you weren't aware; employers typically match 401k to a certain extent. For example if you put 5% of your salary into 401k they'll match it, which means you get an extra 5% free going into your 401k. Every employer has different setups, some will go higher or lower (5% is the highest I've had), some will match every %, some will match half of what you do, (if you put in 5% they'll put in 2.5%) etc.. You always want go put enough in your 401k to at least max out the employer contribution since that's free money. Whether you contribute more than that into the 401k or put any additional into a Roth IRA is up to you, but always get the maximum match if you can.
