Getting keys the easier way
First you need to get the sb_iso_spu_module.self individuals seed that can be found in the metadata header:

Using your console specific eid_root_key/iv (e.g. from metldr dump) and libeeid you can then generate the keys directly by calling
u8 indivs[0x100];
u8 chunk1[0x40] = {0xD9, 0x2D, /*...*/, 0x00};
u8 chunk2[0x40] = {0xC3, 0xB3, /*...*/, 0x00};
indiv_gen(chunk1, chunk2, NULL, NULL, indivs);
Now you have your console specific ATA data key in indivs[0x00-0x20] and the ATA tweak key in indivs[0x40-0x60] :)
About "ENCDEC IV and key"
This key/iv pair set by metldr is your eid_root_key, it's not just used for one purpose. (-> https://nwert.wordpress.com/2012/07/11/eeid-cryptography/)
