Unfortunately taxation legislation is both voluminous and complicated. Although your questions look straightforward, the answers will depend on a detailed examination of your mother’s and your circumstances - that what you pay a professional to do.
If you want evidence of that voluminous nature just take a look at HMR’s own manuals on capital gains tax (CGT) and on inheritance tax (IHT0):

Mother’s sale to you cannot give rise of a CGT liability on you. Whether she has a liability to CGT will depend on her ownership history of the house - if she lived in it as her only residence for all the time she (and her late? husband whose interest she inherited on his death) has owned it then irrespective of whether she gifts, sells at under value or at full (market) value PPR should relieve any realised gain . But it all depends on her ownership history ….

b) How would she qualify for £650k threshold if my father has already passed away?
Yes to a). But if she sells the house to you at less than open market value then, as mentioned previously, the difference is deemed to be a gift to you and she has a reservation on the benefit of that gift from continuing to live in the house which value is added to her own free death estate to calculate any IHT payable.
b) concerns transferable nil rate band (NRB) from your deceased father’s estate to your mother’s estate on her future death.
See relevant section of IHT manual http://www.hmrc.gov.uk/manuals/ihtmanual/IHTM43001.htm
So, for example, if your father has previously died havving left his entire estate (including his share of the house) to your mother (so he used up none of his NRB or threshold) then on her later death she will have her own NRB (currently £325k and not expected to increase before 2015) and another one transferred from father (at current value as of date of your mother’s death). So it was how your father’s (or another previous deceased husband’s) estate was bequeathed that determines whether your mother has one NRB (£325k currently) or up to a maximum of two NRB (£650k currently).

No, I don’t think so assuming she has no mortgage (which can affect stamp duty payable).
tcaller wrote: Can I ask who decides Market Value if we aren't using an estate agent to purchase through? We instruct a solicitor to do the conveyancing .....how does the house get valued and does it need to be legally? On various property valuation websites the house is supposedly worth £575K but one recently sold in the road for only £450K which figure would be used and do they take into account repairs that are required after purchase?
The “open market” value (OMV) can only be an estimate --based mainly on its features (size, condition, etc) and sales of comparable properties – whether by an estate agent, buyer, seller, professionally qualified senior member of Royal Institute of Chartered Surveyors (FRICS) or District Valuer (DV who HMRC use). The financial significance of that estimate to you should influence how much effort (and expense) you spend on substantiating the figure you decide to use. For example if your OMV is £450k, you pay your mother £350k and she has other assets of £100k on her death and a full transferable NRB from your father; then her free death estate is 450k, reserved benefit is 100k and NRB £625k so no IHT payable by some £75k (625- 550 ignoring other things); probable that HMRC will agree to OMV without query as no IHT payable by a fair safety margin.
But if only 40% of transferable NRB from your father then IHT payable of £38k ( =40% of {550-1.4*325}). HMRC would then probably investigate the £450k OMV and the District Valuer could say it was £575k increasing the IHT to £88k (=40% of (550+ 575-450-1.4*325}). So to mitigate a £50k (88-38) problem you may wish to have spent say £600 +VAT for a FRICS valuer who could later argue or contest the DV valuation later on if necessary.
However, as a first step, I’d suggest your Mum tells three reputable local estate agents that she is thinking of selling and wants in writing their estimates of the price she could expect (usually 5% -7.5% below the listing price they advise). If three estimates differ by no more than 10% you are probably on safe ground to take the middle point as evidence for the OMV (assuming there is no development potential). If you are going to need a mortgage then a mortgage valuation would be another bench mark if your mortgage company will agree to release a copy to you (though most mortgage valuations are 5 to 10% below OMV). If the house needs substantial repairs then take photographs of its condition to show DV who would use comparable properties in much better condition to argue a higher OMV than you contend.
So it all depends to a number of factors as how imprtant is the OMV estimate: one of which may be how likely is it that IHT is payable on your mother’s death; if that is likely and the estate agents' three free written valuations differ markedly then a professional valuation may be a sensible cost.
