No doubt.
For me, not using staves until I get to 23 and pull my sireth out of the raider's box has allowed me to comfortably max trapping skills. Being a skill-starved paladin I still have to dump spot, but that's fine for a veteran.
I end up taking my rogue levels at 1, 8, 14, 17 and 20. This is a "pure" 15/5 build, as opposed to a 14/5/1. Here's the skills table:

So far I'm level 15, so it's still basically a regular evasion paladin so far, but it's been super fun re-leveling this build if nothing else for the nostalgia. For weapons I'm mostly using a lit2 falchion.
My guy's skill checks are off the charts, helped along by +3 skill tomes on search, disable and open lock, plus taking all the skill bonuses in the human tree and the mechanics line in the mechanics tree.
At level 15 I'm around 50 skill check. As in, the little dice icon that shows my roll displays a bonus in the high 40s, like +47 or +49 I think, for both disable and open lock.
The high open lock is particularly gratifying, getting both the locked treasure room in chains of flame and the mind flayer "rare" in gianthold on the first try, both with DCs in the 50s.
