Sorry, meant the 8.6% special attack hit cap, not the white damage hit cap. Once you get something like... ~25 hit rating as a Rogue, you should be yellow-hit capped on bosses with full-on combat (5% from Precision, 10 Weapon Skill = 1% Hit, .4% Crit, -.8% Dodge Chance on Target), at which point Crit becomes a more valuable stat.
Barring external influences (like, yes, Combat Potency) and assuming that your DPS numbers are relatively stable... once you have exceeded 8.6% hit, +hit only increases white damage (including Windfury Totem). 15.8 Hit Rating is 1% Hit, whereas 22.1 Crit Rating is 1% Crit. 22.1 / 15.8 = 1.4
If you could magically add either the same amount of Hit Rating or Crit Rating (like looking at socketing a piece of armor), in order for the 1.4% +Hit to be better than 1% +Crit you would need to have 71.4% of your damage come from white attacks. While this _is_ possible in certain situations, especially with an immense amount of Haste stacking (multiple Bloodlusts, multiple Drums of Battle, Dragonspine Trophy, 35% Slice and Dice, passive haste rating) it's extremely unlikely. To use the very-often reposted WWS of Furi's DPS, he gets 67% of his damage from autoattacks.
There are other factors as well, though - effects which can proc on hits (certain haste procs, especially) obviously benefit from an increased chance to land and thus proc - but... as a general rule, try to pick up AP and Crit where you can over increasing your Hit, especially before you start getting heavily into Haste gear (i.e. before Hyjal/BT).
This actually isn't true based on the current theory crafting for combat rogues at EJ. As far as itemization points are concerned, 1agi = 2ap = 1 hr = 1 cr as far as DPS stats are concerned. However, in a buffed raid, 1 hr produces more raw DPS than any of the other DPS stats at most gear levels, with common DPS groups (I personally use an enh shammy + warrior as that is generally what I have). You can check this for individual builds by swapping around gems in the spreadsheet (8hit/8crit/16ap/8agi).
This being said, hit scales in a linear manner (second time I'm writing this this week). You gain the same DPS upgrade by going from 0->10 hr as you would from 260->270 hr. There is no real added benefit gained by stacking hit. However, in general, hit gems will provide you the largest DPS upgrade out of any gem (for raiding). Point being, don't pass on better gear just because it has less hit rating on it. If the item is better, it is better. Just because the combination of DPS stats on the "better" item doesn't include hit doesn't mean that said item is inferior. You have to look at not making crazy assumptions that one stat is just flat out better than another. Crit rating is actually the worst stat for sustained raid DPS on an dps per itemization point scale (according to the charts). However, a good amount of rogue gear has it on! Guess what, it's only worse by a slight amout... so who cares.
For what it's worth, at 308 hit, 1669 ap, and 25.01% crit about 62-66% of my damage comes from white hits (depending on the fight and group comp). I won't be holding on to the hit cap, but for now it's easy to reach with gems and such (and the fact that all of the lower end raiding leather has hit on it).
