Have a few questions about rims/tires! thanks in advance!

I just purchases an 06 tacoma that already has a 2" lift on it. So far im loving it, but due to living down dirt roads, and helping my carpenter father-in-law out, im sure ill end up with a flat tire in some point in time. With that said i have a few questions so i can get the right stuff i need!

1) The tacoma did not come with a spare tire. With that said i would like to try and find the same rim thats already on it to match. ive included a photo to show what kind of rim it is but other then the "m" logo in the middle, i dont see any brand names on it to look it up. so if anyone can help me find the right one that would be great!

2) the truck came with decent mud tires on it LT285/75r16 Mud claw to be exact. with mud tires like this, if i did get a spare tire, would i have to rotate it every so often with the other tires?
2b) also would that size tire fit in the original spot for a spare under the truck, or would that be to big?

3) now for the final question (i think). with the truck having a 2" lift kit installed, the original jack is not in the truck, i have a jack that might work if i put a 4x4 under it, but it takes up 2/3 of my floorboard in the back. whats the best jack options that would (if possible) would fit under/ behind the seats?


thanks again in advance for your help!
