Another sub-panel question and compressor question

[WaterBoyz]

Thank you in advance for your guidance and education and suggestions.

Sub-panel - part 1
Need to add sub-panel to my attached garage.
The distance between the main panel and sub is 51 feet. The main panel circuits have the neutral (white) the grounds (bare) wires on the same bus bar. Electrical code 2011.
At the sub I need:
One 30 amp 220V circuit
Two 20 amp 110V circuits
Two 15 amp 110V circuits

The wiring would be in the basement, running in the ceiling floor joists.
Questions:
Romex cable or?
Wire size?
How many wires?
Solid or stranded?
Breaker size?

Sub-panel - part 2
I need to feed the 4-post lift the 30amp 220V circuit. That connection is 24 feet from the sub. Will ruin it in some type of surface mounted protection be it a plastic pipe or EMT or armored cable.
Questions:
Wire size?
Solid or stranded?

Air compressor
The air compressor will be in the basement with the wiring in the ceiling floor joists and the distance is 87 feet.
Its' motor name plate rating is:
HP = 5 SPL
Volt = 230
Amp = 13.1

Questions:
Romex cable or?
Wire size?
Solid or stranded?
Breaker size?

I think you are looking for free electrical design services. I don't mean to be harsh, but books are cheap and reading forums is free. A better way to approach this is to state your plan and wait for criticism and changes.

Another way to do this is to ask individual questions like, "Can I run Romex cable in my attic joists from my sub panel to my compressor?" (Yes, with provisions, the key word being "in".)

The wire size and breaker protection are a function of the compressor requirements, so please enter the information before the question. Same goes for the lift. The guys here are sharp and willing.

Thank you for your reply, Zeke.

I have basic knowledge but not exact knowledge. Most "rules" are written by people for people in that particular trade. For me, sometimes the books and/or rules are written at a level that is over my head.

The Garage Journal is full of people who have the Trade training and those that have Seat-Of-The-Pants training. I enjoy reading and learning about stuff here that I never knew about or fully grasped during my 40+ years in the working world.

I have scanned/read the forums for info for my situation. I admit, my "search mechanism" is not always the best. There are posting here about sub-panels but none that match my exact situation. I tried to give as much information as possible in my first post to reduce the back-n-forth. I laid out my posting, I thought, so that the responders could just quickly pop in the answers. Sure, I could have posted 3 new threads.

What more information do you need about my air compressor?

I'll get it rolling. Your panel needs sound like a great match for a 60A breaker (in your main panel) supplying some small 60A to 125A panel by three #6 copper stranded THHN or similar wires (black/red/white or black/black/white) and a green #10 ground in EMT conduit.

Is the lift hardwired or does it have a factory plug? How about the compressor?

EDIT: is the compressor on the subpanel? You only listed one 240V circuit.

Thank you, AL.

The lift will have a twist plug connection since I will be moving it around the garage in two different locations.

The air compressor currently has a NEMA 6-20 20A 240V 3-prong plug that is not the original.

FWIW it depends on the actual run, but if you don't need conduit for protection, 2-2-2-4 AL SER is cheaper than what I said before. It would give you a 90A panel which is kind of overkill but not more expensive. You can staple the SER to the joists as long as it's not subject to damage. No idea what your basement looks like or what the entry to the garage will be like.

The joists in the ceiling of the basement are the OSB style I-beams. Already have many "Romex" wires running through them. Home is 2 years old. Your standard ranch with full basement.

The entry into the garage is simply drilling a hole in the outer rim board and then the drywall into the garage. Then a surface mounted hard pipe about 4 feet to reach the surface mounted sub-panel box.
