Unable to connect SF300 to Catalyst 3750

I realize this has been dealt with several times and i have reviewed every article and researched this until its causing sleepless nights but i can't even get them to talk to each other.  Granted, I'm a rookie and thought i could figure this out but after 3 straight weeks of brain busting all I've accomplished is a huge waste of time.

I inherited this and lets just say that based on past findings of predecessor projects I have reason to suspect anything and everything he touched to be.... 'not up to normal standards'

 

SF300 has been wiped and is not in production so I can do anything i wish to it.  3750 is not only in production but appears to be the core switch handling 5 VLANS, of which 2 of them I am no longer using.  Goal is for sf300 to handle two VLANs via ports GE1 and/or GE2 and trunk to the 3750 port fa6/0/47. VLAN10 (192.168.3.1) for data and VALN150 (192.168.33.1) for VOIP.  VLAN80 appears to be the native VLAN in the mix, VLAN1 is present but in different states of configuration depending on the switch being viewed.  There are 4 other switches involved so while I can't make global changes to the 3750 that might impact other switches I can choose one port to do what I wish with.

 

That being said, here's port 47 of the catalyst 3750:

I have no ego that needs feeding so if anybody sees anything at all out of whack or odd or just plain wrong pls tell me.  I know the ports should be access but until I can figure out how to get started I simply tried to open everything up.

 

also, i can talk to the switch 3750 if I plug it into one of its access access ports but I think that would defeat the purpose of using VLANS..?  I am so baffled that I don't even know how he got anything to work altho I do see native VLAN mismatches in the other switches connected.  Traffic does pass thru them, tho, so I shouldn't criticize as I can't get anything to work.

 

drowning in a sea of tears of frustration....

 

any additional info at all you might need , pls ask.  and pls don't assume knowledge of where none exists so when giving instructions pls keep that in mind.  and This may be a puzzle to you as nothing i've seen yet leads me to believe things have been done corectly

thx
