EU student with PSS end date and forms

I am an EU citizen with a Pre-Settled Status, habitually resident in England for nearly 5 years.
I have enrolled in an undergraduate degree and I am trying to figure out how to apply to student finance for a Student Loan.
1. Apparently I cannot apply online and need to fill a paper application. I have found 2 possible application forms.
One is this one : https://assets.publishing.service.gov.uk/media/68c1a07deeb238b20672a961/eu_eu25n_form_2526_o.pdf
The other is this one : https://assets.publishing.service.gov.uk/media/67d85b3479f0d993dfb11fcb/eu_tfl_request_form_2526_o.pdf
Which one should I fill considering that I also want to make an application for a Disabled Student Allowance?
2. Same with the Disabled Student Allowance there are two forms, DSA1 (full form) and DSA Slim. Notes say if you also apply for a student loan you should fill DSA Slim but Open University advises to fill DSA1 so I am confused.
Should I fill DSA1 or DSA Slim?
3. Finally, my pre-settled status end date is in November 2025, during this academic year that I am applying for funding. The government has extended every pre-settled status for 5 more years, so in reality my pre-settled status no longer expires (and I will obtain Settled Status in November 2025 anyway). Yet so far all the information I have found about eligibility for funding says that I would not be eligible if my pre-settled status ends during the academic year I am applying for funding and both application forms do require my pre-settled status end date.
What is happening exactly? I am thinking about attaching as evidence the email I received from the Home Office about my pre-settled status extension, would that be enough for me to be eligible? Will they consider it?
