Importing isn't inherently illegal in itself. If all laws and regulations are followed, then nothing is wrong. If you did it as you said "researched", and everything is properly observed, then there is no issues. If you didn't, then you took a great risk and got very lucky; not to mention set a horrible example to others who may try and fail at what you did. That and possibly give airsoft more bad press at the same time. So here's to hoping you did follow the rules and didn't take a risk for a gun that's available in Canada.
On to your questions. It's unlikely that your gun will settle that much in a short time ...if ever. Find out what your local hard cap is, and aim to come in 20 FPS or so under it. Find a legitimate gun doctor to swap springs for you. For example, if the hard cap is 420 FPS, grab a spring that should land you around 400ish or so. A few FPS won't make a large function difference, but hard caps are absolute. 421 FPS will get you sent home in this case. Remember that FPS changes due to temperature, upgrades, etc; so don't think your smart by trying to be one or FPS under the hard cap. You may be good one day, and not the next.
If you want to run a tracer unit, don't get an extended inner barrel. If your inner barrel runs into your tracer unit, the your BBs won't glow, as they won't be subjected to the light inside of it.
ďREALITY IS LIKE A STONE. TO MANY ITíS HARD AND COLD, THEY CANíT HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESNíT DO THEM MUCH GOOD. TO OTHERS ITíS STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.Ē
