Answer 1

Your question,is not clear in mind.

But may be your want to increase your current product price 2.5 ,3 times.

Best Option:Update product price Import/Export using Csv

So in this case,Better idea to export current products price,sku in csv sheet from System>Import/Export section then increase those by 2.5,3 ,and Import that update sheet.

Using code:

Get Product collection and update product by logic:

$collection=Mage::getResourceModel('catalog/product_collection');

foreach($collection as $product):
  $CurrntPrice=$product->getPrice();
  // Due some logic
  $tempPrice=2.5*$CurrntPrice
  // below code use for time format 
  $product->setPrice($tempPrice);
  $product->getResource()->saveAttribute($product, 'price');
endforeach;
