Been having greif with my gearboxÂÂÂ

basically I have to push it hard into first and drag it hard into second cos if I dont it will flick back into neutral!
moving to 3rd and down into forth is fine and 5th no probs.
Just wondering what might be the problem and if its going to empty out my weee savings.
also the clutch it feels ery light the biting point is about half way up but it doesnt feel like it grabs the gears more slips into them if you know what I mean?
Any help would be great and recommendations for a vw garage in London thats good would be great as it looks like I need a mechanic
forgot to add its a Vw golf 1.6s 2001
