On a practical level, yes, it has influence, as the faster/agile the target ship is in relation to yours, its harder to land a collision. On a mechanics level, no.
On a practical level, no, especially if you are bumping solo. You can "tackle"a pod with a bump, but because it it has 0 align time to warp, the effect is reduced to zero. On a mechanics level, you can still bump a pod. (afaik, Ive never tried).
