2009 Ford Escape Hybrid - Ignition Coils and Spark Plug Replacement

I’ve purchased the parts and done my research. Basically, I am seeking some insight here to gauge if my understanding of the procedure is sufficient, that I have acquired all the necessary parts, and to get some tips/tricks/warnings to make sure I don’t cause additional damage.

Parts

1. 4 vehicle-matched ignition coils
2. 4 vehicle-matched spark plugs
3. Replacement intake valve cover gaskets
4. Replacement EGR valve gasket
5. Dielectric grease

Tools

1. Torque wrench
2. Matching spark plug socket

Procedure

1. Disconnect and remove intake valve cover (I know this step contains several steps within it, but for brevity I am simply summarizing it as this)
2. Protect intake valves
3. Disconnect cables and bolts from each ignition coil – note which cable belongs to which
4. Use socket to remove and replace spark plugs
5. Apply dielectric grease to end of coil boots and reinstall; insert bolts and tighten with torque wrench
6. Clean intake surface, apply gasket to cover, reinstall
7. Reconnect all cables, retainers, etc. – tighten with torque wrench. Also clean EGR valve surfaces and install new gasket
8. Once all parts and covers replaced, test engine waiting for a clean idle, test drive

Key things I want to know:

1. Steps where I should exercise more caution; trouble points; high risk of damaging vehicle points
2. Complexity of this repair
3. Anything else that will help me execute this successfully

I think I have a good idea of what and how to do this. Quoted cost of this repair was enough of a sticker shock to send me looking for DIY solutions.

Thank you in advance for your replies and advice, and I apologize for any mistakes in the above – I’m not a mechanic by any means.
