A lot depends on whether your car has a trailer hitch, what type of bikes you are moving and your physical limitations. If your bikes are carbon fiber, you don't want a bike carrier that clamps down on the frame. Roof top carriers normally don't and most lower end hitch mount carriers do. My favorite for road bikes is hitch mounted Thule that clamps the wheels, not the frame.

If you can manage lifting your bikes onto a rooftop carrier, then that may be a good option for you. I don't recommend rooftop for heavy bikes and don't like the thought of driving my bikes into a garage door opening by accident.
Realistically, most floor pumps are adequate but if you want high quality, you will be looking at spending 50-120 dollars. the two mentioned above are good. Specialized has decent pumps but in my opinion, Lezyne
http://www.lezyne.com/products/floor-pumps is the current gold standard. Get one with an accurate guage, high pressure capability and dual heads for schraeder and presta valves.
Locks- sorry, I don't use them other than a Kyrptonite cable lock when stored in my garage.
Helmets- Like your bike, get one that fits or can be fit to your head shape. Most safety analysts don't like to see points on the helmet although that is the current trend for aerodynamics and marketing. Bell/Gyro, Specialized and numerous others are good. I like the more expensive helmets with a carbon fiber weave. They are designed for multiple impacts as opposed to a single hit. This is an area I don't mind parting with a couple hundred dollars every five years. Yes, they do become brittle with age and yes, discard them after an accident.
