Coverage of topics for L1 , L2 and L3

in CCNA & CCENT
Hi All,
I am trying getting to know / brush up the skills on L1,L2 and L3. Query is what to cover ?.
I am thinking below topics..
L2 : VLAN , STP ,RSTP , VTP ,ARP ,BOTTP and DHCP
L3 : RIP,OSPF,BGP and IS-IS
IP : IP Addressing , Subnettting , Supernetting , IPv4 and IPv6
No idea on L1 .. at all what to cover..? .
I need inputs from you like , what else should be covered here .. ? .
Final objective is to get to know the domain of L1,L2 and L3 technologies.
Thanks

Out of topic but i thought hubs are obsolete in the market?
They are and should never be used especially in a production environment. I think they are shown so much in CCENT because they highlight why you would use switches more in a network as it shows the effects of collisions.
I've certainly not seen any for sale any time recently

barberj66 is correct, though I have heard of a few really small companies utilizing hubs.

Correct...I only gave the example for exam purposes and not for real world use.

I saw a 30 user environment which had a hub here:
