i'm trying to learn better living through chemistry by queens of the stone age and so far i've been stuck on two parts.

the first part is at 2:51. the tab i'm using says

||-------------------------------------------------10h12-----||
||o--------------------------------------7h9----------------o||
||----------------------5h7----7h9--------------------------||
||------------5h7---------------------------------------------||
||o-----------------0--------0--------0-------0------------o||
||--------------------------------------------------------------||

firstly i don't hear the open notes in the song, so i don't play them. and i actually play it like

||-------------------------------------------------10h12----||
||o--------------------------------------8h10-------------o||
||----------------------5h7----7h9-------------------------||
||------------7p5h7-----------------------------------------||
||o----------------------------------------------------------o||
||-------------------------------------------------------------||

is this wrong? should i practice it like the tab says?

second, is a part on the solo at 3:13. after the 9-12-7-6-7 it goes

||------9--------9-----------------------------------------------||
||---9---9-7-9---9-7-9-6-9-7-9-6-9-7-9-------------------|| x2

||---------9----------------------------------------------||
||----------9-7-9-6-9-7-9-----------------------------|| x??

anyway i learned to play this part with my ring and index finger, but i think i'm going about it wrong. should i play it with all four fingers? which would be faster? so far the fastest i've been able to play it is 88BPM.
