Answer 1

If SQL Server, you can use a Split/Parse function to normalize the string
Declare #YourTable Table (YourField varchar(25))
Insert Into #YourTable values
('1.3.45 TU 3'),
('1.2.5 TU 8')
Select A.*
,NewField = B.String
From #YourTable A
Cross Apply (
Select String = ltrim((Select cast(RetVal as varchar(25))
From (Select RetSeq,RetVal=Right('00'+RetVal,2)
From [dbo].[udf-Str-Parse](replace(YourField,' ','.'),'.')
Where Try_Convert(int,RetVal)>=0 ) A
For XML Path ('')))
) B
Returns
YourField NewField
1.3.45 TU 3 01034503
1.2.5 TU 8 01020508
The UDF if needed
CREATE FUNCTION [dbo].[udf-Str-Parse] (#String varchar(max),#Delimiter varchar(10))
Returns Table
As
Return (
Select RetSeq = Row_Number() over (Order By (Select null))
,RetVal = LTrim(RTrim(B.i.value('(./text())[1]', 'varchar(max)')))
From (Select x = Cast('<x>'+ Replace(#String,#Delimiter,'</x><x>')+'</x>' as xml).query('.')) as A
Cross Apply x.nodes('x') AS B(i)
);
--Select * from [dbo].[udf-Str-Parse]('Dog,Cat,House,Car',',')
--Select * from [dbo].[udf-Str-Parse]('John Cappelletti was here',' ')

Where are the zeros? You want something like this:
select ('0' + -- initial zero
replace(replace(replace(#Column, 'TU', '' -- remove TU
), '.', '0' -- replace dot with zero
), ' ', ''
) -- remove space
)
from Table;
