To answer your questions:
Did all the 2x10 pass over the post you are removing all the way to the next because if they spliced them over the removed post they would not help pass the load over the new span.
The 3 - 2x10 pass over the lally column. Prior to hanging the LVLs I can see that the 2 - outside 2x10s were spliced over the column I want to remove. I could not see the 3rd 2x10 that was sandwiched in between them. For purposes of calculating the stregth of the 3 - 2x10s I would say they are all spliced over the column I want to remove and therefore of no support help for us.
Are you removing 1 post from each end (2 total) or just 1?
I want to remove only 1 column, on one side of the house.
What is the foundation under the center post you are adding all the load to?
The house was built in 1970 and the town does not have the original plans. I'd assume that the builder put some sort of a footing under all the lallys but I don't know for sure. There are no signs of cracking, etc in the foundation nor floor areas around the Lallys.
Which walls on the first floor are load bearing and where?
On the 1st floor directly above the girder is a wall between the livingroom & diningroom with a 6' opening (header above that). This wall supports the second floor master bedroom. On the second floor directly above the lvrm/dnrm dividing wall, there is a partition wall seperating 2 bedrooms. In the attic above that there are only the celing joists so the 2nd floor bedroom partition walls support the attic rafters. The roof is supported on the outside wall.
There are no bathrooms on that side of the house so we have just the dead loads for the 1st & 2nd floors with the supporting walls as described above along with the live loads from the lvrm/dnrm & bedroom furniture/closet live loads.
-------------------------------------------
I figured that the footing under the center lally column should be strong enough to pick up the extra load and am willing to take a shot at that. I'll just have to monitor it to make sure nothing starts sinking.
I also figure that since 2 of the 3 triple 2x10s were spliced over the lally I want to remove, there is no support contribution from the triple 2x10s sandwiched between the 2 new LVLs. The 2x10s in that space then become a "holder" for the 2 new LVLs (by bolting them in place to the 2x10s).
As a side note, if the center stick of the triple 2x10s is NOT spliced over the Lally I am removing then we pick up the extra load capacity from that but we're calculating the LVLs to support everything on their own so that does not matter.

--------------------------------------------
The question becomes then:
Do the 2 - new 91/2 LVLs at a span of 11'4" deliver sufficent load support for the 1st floor, second floor and attic joists.
My thinking is that if the 2 - new LVLs at 11'4" meet or exceed the maximum load capaciaty of the triple 2x10s at 6' then i can take out the Lally.
Can someone tell me the maximum load capacity of the triple 2x10s spanning 6' vs the maximum load capacity of the 91/2 LVLs spanning 11'4" (and installed/fastened as descibed) and if the LVLs over 11'4" will support what used to be supported by a triple 2x10 over 2-6' sections?

I think you are look at a real problem if you don't stop now and call a lumber yard that has an engineer on staff to firgure you load and needs. They do this for free, NOT A BOX STORE they just guess.
I purchased the LVLs from the lumber yard and went over the design with a counter guy there (I've worked with in the past) however he is not an engineer and did not do the load calcualtions.
