Paying my student loans (UK) and New Tax Year Deductions?

So my parents have given me the money to pay off all of my student loans (£14.000) and i am currently working. If i pay off the student loans now, will i still be deducted in the new Tax year (April 6)

How will the HM revenue know i have paid this money off and not start deducting from my wages.

Anyone who has paid this money off, please guide me through as i don’t want to be pay it off and only to find them deducting me in the new tax year.

on my pay check it say after tax deductions what does that mean.?

they garnish my wages and on my last pay check it shows a total of taxes taking out and underneath that it says after tax deductions what does that mean.

Would it be a good idea to set up a traditional IRA for tax deductions I need this year, and a Roth later?

My consulting business did well enough this year that I had a bit of money due to the IRS. I planned on setting up an IRA this year since I’m in my mid-twenties. I like the tax-free potential of the Roth, but I also need to lower my AGI this year. Would it make sense to open and contribute a portion of my wages to a traditional account and deduct what I need to break even on taxes, and throw the rest into a Roth account? Not exceeding the ,000 limit on contributions of course… The fees on the accounts should be negligable, considering that I’m working primarily with an Internet broker.
25% is my current tax bracket.

when does the IRS withhold garnished wages from the employee, is it before or after tax deductions?

My friend found on his check stub that it said "ATT1" under after-tax deductions. He’s wondering if his wages are garnished? Would it be under "tax dedutions"? or under "after-tax deductions"?
