I have good news for you - Legacy will do everything you're asking about.
The free Standard edition is a perfectly adequate program, and many people are happily using it. I suggest you download it and import your GEDCOM file, and see if you like it. The current version is 22.214.171.124
When you decide it's just what you need, and you want to unlock the extra features, go and buy the Deluxe edition - it is the same program, just with extra "bits" made available to you. You'll be sent a key (a code) that you copy into the program to unlock the Deluxe features.
If you never feel the need for the Deluxe features, carry on using the Standard edition. There's no limit on how long you can use it, or how many people you can have in your file (only limited by your hard-disk space).
Hope this helps. :-)
