Hey mate... Rim Locks are a small device installed on the rim that basically clamp the tyre bead down onto the rim from the inside.
This stops the tyre/tube from spinning on the rim under hard acceleration and tearing out the tube valve.

Heres a thread about fitting rim locks for ya... Its pretty straight forward!

DOnt know anything about the rims, spokes or axles though... Im sure someone here will jump on and help ya out!

there are rims that take 12mm axles on ebay

cant you just get some new bearings with12mm bores.
pop the old ones out, measure the o/d and buy another pair with 12mm bores from a bearing shop.

i bought some used rims off a thumpstar that were 15mm axles.
i had replaced my bearings recently in my old wheels, so i popped them out and fitted them to the new wheels
problem solved

iv never come across a bearing that you can convert 15mm axle down to 12mm..

but yeah there are plenty of 12mm axle wheels available, post a pic of your bike so i can see what hubs it needs..

and yes you can respoke them but its not an easy job or cheap if a shop does them... you could buy 2 sets of wheels lol
