comment Can I use an old cog for my new hub?
No amount of messing around with the chain tension would change the gear ratio of a 17 tooth cog to match what you obtained from a 16 tooth cog. The gear ratio is purely the ratio of the tooth count of the driving gear to the tooth count of the sprocket. As far as the actual chain tension goes, you probably want to to be getting a new chain when changing sprockets anyway.

comment How much pressure can mountain bike tires take?
The maximum pressure stamped on the sidewall of MTB tire is almost complete garbage.

I think this is what was intended.

comment Why don't brakes come with 'Safety Levers' any more?
Indeed, it's silly to call these things "safety levers", since all the actuators in the diagrams are levers, and brakes are for safety. Thus they are all "safety levers".

comment Chain slipping off derailleur jockey (need suggestions ASAP)
terminology problem: that is not a jockey wheel The jockey wheel is the one that actually applies pressure to the chain to move it from one cog to another. A disk jockey changes disks; this jockey changes gears. The lower wheel picks up the slack from the chain. It is called the tension wheel.

comment what kind of grease to use on front shocks
"The reason is that these are subject to high, fast friction and a lot of heat, so you need lubricants that are developed to handle these conditions" -- almost comical in the context of bicycles. What technical lubricant (i.e. not bacon grease or corn oil) cannot handle the pressures or temperatures that occur in some bicycle fork?

comment How much of a difference will I notice going from a Mountain bike to a road bike?
The commuter bike alluded to in the very last sentence has little to do with what is described in the rest of the answer.

There are bikes which combine the more comfortable seating position with smooth tires (but not necessarily very narrow), with some optional suspension (more so nowadays), with lighter frames that take cues from road bikes. These are known as "urban", "commuter" or "touring" bikes and serve people who actually use bikes day in, day out, year round to get from one place to another. (Not to be confused with "cruiser bikes": bicycle shaped props for nostalgic escapades.)

It's not the width of the MTB tires and the contact that slows you down. It's the squirming of all those rubber knobs that are constantly being bent out of shape. You haven't made a fair comparison with, say 1.95" or 1.75" smooth, "road slick" tires on your MTB.

@Trengot Cannot make head or tail of your comment, or what it is replying to.

comment Are aerodynamic rims worth additional weight?
For normal recreational cycling, you can take the $1500 that would go for a pair of wheels, and buy yourself three very decent bicycles. Or, buy one bicycle and put the rest of the money into an investment fund that, at maturity will be used to replace the bicycle, with the remainder re-invested in preparation for a third bicycle.

comment Are aerodynamic rims worth additional weight?
The missing information here is how the weight is distributed. Any of the extra grams which are in the hub don't matter much as those that are in the rim. The rotational acceleration of mass in the hub is negligible, because it is proportional to the square of the radius. A piece of mass at 13" from centre has 169 times the moment of inertia compared to that same piece of mass at 1" from centre. These weight figures are for the entire built wheel, right? Spokes, hub and all.

comment How to get more tire clearance with caliper brakes?
From the picture it looks like the pads are not sufficiently curved to match the curvature of your wheel diameter. This could be half your problem. Find pads that are more curved.
