A good all around kit to start you out on would be the standard Auto Kit.  I would get the 4 channel model, trust me you will need all 4 channels and later you might want more, .  I use two 4 channel Picos together.  But a 4 channel standard Auto Kit is a good way to start.  You get more stuff in this kit than the Diesel Kit.  Also if you can afford to I would also recommend getting a Wps 500 Master Kit.  I have one and use it quite frequently.  I use it to detect low side fuel pressure problems on Cummins ISL, ISC, Caps, Common Rail.  It is also very handy for finding intermittent misfires in the exhaust.  Plus you can use it for Engine Integrity breathing tests.  Another application you can use it for is tapping into Kneeling blocks and looking at the pressure going through the block and also using it to check the hold valve integrity.  Plus you can put a amp clamp on the coils to see if the valves are mechanically opening.  Anyway, let me know if you have anymore questions and if you would like to talk to me on the phone just pm me and I will call.   Which Transit Authority do you work for?  I know Jim Davis from Pierce County Transit and I also know Mark Dalton from King County Transit.  Once you get in the group you will not be disappointed, trust me.
Been a Picogroup member since 2013 and the support here for the scope and the additional training you get is phenomenal.  Plus there are some other Transit guys on here.  Jim Davis is one and there are a few more, can't remember their names though.  Plus there are some real good HD guys on here that work on Semis, Boats, Heavy Equipment.  So in other words you are going to get help in the journey of learning this equipment.  This is a good group of guys on here, very professional and we don't put up with any nonsense in this group, everyone takes their job seriously on here.  Any more questions let me know.
One more thing, if you work on a lot of Hydraulics you might want to look into getting the WPS 600.  The Nerd group can order it for you.  I don't have one yet but it's on my wishlist.  Got to play with one at the Community College I instruct for.  Had it hooked up to a bulldozer looking at the blade pressures, very cool!
