SOAs are gonna give you somewhere in the ball park of 5" lift. a MAXED TB crank is gonna give you 1.5-2" lift. 29" tall tires will fit on stock rims at stock ride height, in fact you can stuff 30" worth of tire in there.
If you're that hungry for ground clearance, going up an inch on the bars isn't gonna hurt you too bad, but yes, TB cranks are hard on halfshafts (mainly the boots) and especially hard on Ball Joints. to match the rear, you can go with a set of lift shackles, or an add-a-leaf to get the altitude. Your other option is to leave the suspension as is, get a body lift (they can be found for under $200 Canadian) and clear 31" tires. GenII b/l's max at 2" for some reason, while GenI b/ls max at 3". Smart money is to start off with the b/l, get some tires, and the start saving like the devil to get either a Trailmaster lift, or ape it and do an SFA conversion.
Oh, and if your Heep and Toylet driving 'wheeling buddies keep telling you that you can't 'wheel an s10, laugh at them. laugh in their face. You can 'wheel circles around anything in a stock s10 (I do it all the time in my Blazer) if you know how it handles, and finesse it.
