Hard to answer most of your questions because we do not know where you live and what rules are in effect.

Most conversions are registered only in the owner's mind.

There are a lot of ways to convert- assuming you are electronic fuel injection, this is a daily driver car, AND NOT METHANOL as fuel;
1) start working your way up in ethanol % starting with a 30% alcohol blend, then 10% per tankful thereafter until you reach 50% or a point where the car starts to be difficult in cold start, runs slightly rough, or looses power on acceleration. If no effect at 50% then work up more slowly in 5% increments until you detect something amiss. Avoid wide open throttle. Once you experience anything that just does not seem right or a check engine light then back off 5% in ethanol right away. watch with a scan tool that has live feed to see what trims and injector duty cycles are doing.
2) Or go to larger injectors right away (approx 25-35% higher-by doing step one first you can get a better sense of current pump or injector capacity)
3) Or put an aftermarket kit on it that simply adds injector spray time to the computer's normal command (injectors and pump capacity must still be adequate for this to work really well)
4) Or increase fuel regulator pressures to get more fuel- also needs pump to be large enough to overcome the higher pressure and still deliver more fuel.
5) Or a combination of the above.

Change fuel filter after 3-4 tankfulls if the car is an older model (likely to have gums/varnishes coating tank walls that will be cleaned). You do not want to be pushing the pump and injector limits while having a restricted fuel flow.

Give us full data on what the vehicle is, your goal in this conversion, and how this vehicle will be used or you are only going to get partial or inadeqaute answers that may not work for you. For example- if you do really want to use methanol then what needs to be done is a lot different.
If you are racing- again- it will be different.

Last i checked, its technically illegal to convert a gasoline powered car to an E85 powered car per the EPA.
