About to pull trigger on IMS job - can I get some opinions?

[speedyspaghetti]

Hey guys -

So my indy (Bay Area, CA) quoted me $3,340 for the IMS bearing from LN, clutch kit, and the miscellaneous parts.
Break Down:
- Clutch Kit - $831
- LN IMS Bearing - $849
- Labor - 9.7hrs @150/hr = $1,470

A - Does this seem like a fair estimate? Is the Sachs clutch kit of comparable quality?
B - Is there anything else I should have him look at / do while he's in there?
C - I've replaced basically everything on my front and rear suspension DIY - how challenging would this be to do myself? Obviously I don't want to f-up my car, but it would be rewarding and I could save about $2k by doing it myself.
