How to change limits?

I bought a template for WordPress and now I installed it and try to setup a demo. There are some special limits:
max_execution_time = 30
memory_limit = 256 M (Local Value), 128M (Master Value)
post_max_size = 8 M
upload_max_filesize = 8 M

But developers of my template recommend the following values:
max_execution_time 180
memory_limit 96M
post_max_size 32M
upload_max_filesize 32M

I could not install the demo, because I have such limits. Is it possible to change something or should I change my tariff?
