Please help me find the rhythm!

Well that's a "shuffle".  So you can either quantize to eighths and keep increasing your strength until you get what your after...probably around 63-65 perhaps.  Or...look in your groove templates and find an appropriate 8th shuffle feel.
 
PS:  My menu nomenclature might be a bit off as I'm not at my DAW now.  But I'm sure someone else will chime in presently also.

Yup...8th triplets will do it.  But it will lose a tad of true laid back shuffle feel if he just hard quantizes to 8th triplets.  Might get a little mechanical.  Give both a try there Erik and see which works best for you.

Yeah, if you want a laid-back feel, using triplets might be too rigid.

Actually I see there's a "Swing" control in the Quantize dialog, so you might be better off quantizing to 8th and playing with the Swing and Strength. And I guess that would avoid moving any notes that are too far off into the middle position of the triplet.

Oh I see that's already answered! Thanks a lot for the thoughough guide Karyn. That will save me a lot of time. Thanks a lot everybody. I really appreciate it.
This forum rocks

I always use 1/8 triplets for swing but using straight 1/8s and adjusting the swing in the quantizing window might make your score easier to read if you don't swing all the way to triplets.

Sonar does not display swing in a friendly manner, and, honestly, most printed sheet music just uses 1/8s and with a note at the top to indicate swing.  I write swing as 12/8 instead of 4/4 but most musicians hate that.
By the way, no need to be embarrassed at all.  I have known seasoned producers with gold records who were confused by this.  They knew the feel they wanted but did not know how to express it in music theory terms.
