have tried to answer your questions in bullet points:
- Its an online application, which you then print out, check this sticky link:
http://www.immigrationboards.com/immigr ... 65576.html
- You can sponsor them
- This is a list that i have drawn up for my own in-laws visit in June, they will be applying next month, still missing things i believe, but i am updating it as i read other post and doing research.

Online Application Printout
Original Passport
4 Passport Size Photographs as per UKVI Standards
Old Passport(s)
Marriage Certificate
Documents confirming source of income (Translated)
Property documents (Translated)
Six Months Bank Statement
Covering Letter from Applicant
Sponspor

Sponsor's Payslips (6 Months)
Sponsor's Bank Statements (6 Months)
Sponsor's Accommodation Proof - i.e Property Deeds
Sponsor's Utility Bill Copy - i.e Gas\Electric or Council Tax or Water Bill.
- Money questions i can't answer, i'm sure you need some disposable income after expenses to show you can support 2 extra people and i don't know how much savings you need to show.
- See link above
- 6 months for standard visit visa, but reading the forum its not good practise to stay the whole 6 months, as it is a visit visa not residencey. It may harm future visits if you do.
Hope this helps....
